GENERAL
Lochinvar CPM Boilers are certified for use on the following flue categories:
Installation type Category
Description
B23
Open flue
An appliance intended to be connected to a flue that evacuates the products of combustion to the outside of the room containing the appliance. The combustion air is drawn directly from the room.
C13
Closed Flue
An appliance connected to either a concentric or twin-pipe flue system with a Horizontal flue terminal. Both the air inlet and flue exhaust must be in the same pressure zone.
C33
Closed Flue
An appliance connected to either a concentric or twin-pipe flue system with a Vertical flue terminal. Both the air inlet and flue exhaust must be in the same pressure zone.
An appliance connected to a common air inlet and flue exhaust system, which is designed for more than
C43
Closed Flue one appliance. This common system has a single air inlet and flue exhaust and is part of the building not
the appliance.
C53
Closed Flue
An appliance connected to a twin-pipe flue system with a Horizontal or Vertical flue terminal. Both air inlet and flue exhaust may be in different pressure zones.
An appliance intended to be connected to a separately approved and marketed system for the supply of
C63
Closed Flue combustion air and discharge of combustion products (i.e. other than that supplied by the water heater
manufacturer).
An appliance connected via one of its ducts to a single or common duct system. This duct system consists
C83
Closed Flue
of a single natural draught duct (i.e. not incorporating a fan) that evacuates the products of combustion. The appliance is connected via a second of its ducts to a terminal, which supplies air to the appliance
from outside the building.
All installations should comply with the requirements of:
1. For appliances up to 70kW net input- BS5440-1:2023- Flueing and ventilation for gas appliances of rated input not exceeding 70 kW net (1st, 2nd and 3rd family gases). Specification for installation of gas appliances to chimneys and for maintenance of chimneys. a. Refer to drawing 1 and table 1 for details of terminal locations.
2. For appliances over 70kW net input- IGEM/UP/10 Edition 4 +A: 2016 – Installation of flued gas appliances in industrial and commercial premises, specific attention should be paid to the following sections. a. Refer to drawing 1 and table 1 for details of terminal locations. b. Horizontal terminations shall be located according to the minimum distances given in table 1, and subject to the risk assessment criteria shown in table 2. c. Horizontal flue terminations (other than for fan dilution systems) must not be installed for any single appliance or group of appliances with a total nett input exceeding 333kW net heat input. d. For any single appliance or group of appliances with a total net heat input exceeding 333 kW, the general requirements of IGEM/UP/10 Edition 4 +A: 2016 shall apply and approval must be sought from the Local Authority prior to commencement of the installation.
3. The Clean Air Act for installations exceeding 333kW nett input.

TABLE 2 RISK ASSESSMENT ACCORDING TO BS5440-1-2023
Further to the requirements in BS5440-1:2023 Annex D and Figure C.8, table C.1 the following risk assessment gives guidance for the positioning of horizontal flues. This form should be completed before work commences and undertaken by a person who is competent to undertake the risk assessment.
Type C appliances with net heat input not exceeding 70kW Low level flue discharge risk assessment (including net heat input for groups of appliances)
No. Regarding the flue position
No Yes
1 Will the flue terminal contravene the positions set out in table C.1 for room sealed chimney outlets?
No Yes
2
Will the terminal be sited in a position that will likely allow products of combustion to build up (e.g., enclosed by adjacent structures)?
No
Yes
3 Is the termination in a light well?
No Yes
4 Is the termination within a carport without two unobstructed sides?

5 Will the termination be in an area that might have combustible material in the vicinity?
No Yes
6 Will the termination be in an area that might have hazardous material in the vicinity (e.g., petrochemicals)?
No Yes
7 Will the termination be sited within a covered walkway? 8 Are there any restrictions stopping the fitting of a terminal guard if required? 9 Will the termination discharge over a boundary?
No Yes No Yes No Yes
10 Is a plume management kit required to circumvent the termination distances as required in table C.1?
No Yes
No. 11 12
No.
Nuisance considerations Is the termination sited over a pathway that is likely to cause nuisance (e.g., head height or pluming towards users)? Is the termination likely to cause a nuisance to neighbours? Chimney/flue routes Will the flue be installed in a void that will not be able to satisfy a full visual inspection?
No Yes
No Yes
No Yes No Yes No Yes
Are there any restrictions that will prevent the flue from being supported throughout its entire length?
No Yes
Do the flue materials contravene building regulations (e.g., high risk buildings)?
No Yes
Will the flue route pass through any fire protected areas without the ability to maintain its protection?
No Yes
Will the flue pass through another dwelling?
Is the flue likely to be damaged due to its route/location (e.g., materials stored on it in a plantroom or storeroom)?
No Yes No Yes
Does the flue affect the integrity of the structure it is in (e.g., lintels, cavity trays, barriers, or membranes)?
No Yes
If all answers are Blue, then the flue position should be suitable
If any answer is Orange, then the flue position is unsuitable, consider revising the position or type of flue outlet or contact the local Environmental Health officer for assistance and/or approval

FLUE SYSTEMS USING FLUE NOT SUPPLIED BY LOCHINVAR TYPE C63
In general, boilers are certified with their own purpose supplied Concentric or Twin Pipe flue systems, C63 certified appliances allow the installer to use other flue systems when installing the boiler however, they must be of a suitable minimum standard as per table below.

Aluminium flue pipe must not be used on this appliance as it may lead to premature failure of the heat exchanger and will invalidate the warranty.
COMMON FLUE SYSTEMS
Lochinvar can supply a PP common flue header see separate guide available at www.lochinvar.ltd.uk
Alternatively the installer can use a flue installation specialist to design and supply a separate flue system under the flue designation C63 using the specifications shown on page 13 and information in the table below.
Any installations using flue type C63 must be designed and installed in compliance with any local Building or planning regulations, but as these systems use a flue system not supplied by Lochinvar, Lochinvar cannot comment / advise or provide support on the design of this type of flue system. To design such a flue system, the installer/contractor must consult a specialist flue supplier who will be responsible for the design and installation of the separate flue system. When designing the type C63 flue system, the instructions in the Installation Manual, provided with the boiler, must be taken into account. Lochinvar will provide pressure loss figures for the specific units, but other than that, Lochinvar cannot provide support on Common Flue requests because flue certification is limited to the certified categories in the table on page 2. Lochinvar cannot accept any responsibility for Flue system design.
Available pressure at the flue gas outlet Flue Gas Mass Rate (G20) 96% (g/sec) Flue Gas Mass Rate (G20) 25% (g/sec) Flue Gas Mass Rate (G31) 96% (g/sec) Flue Gas Mass Rate (G31) 25% (g/sec)

The CPM boiler range does not have an internal Non Return Valve (NRV) as such any flue must be designed on zero or negative pressure unless a suitable NRV is fitted and if necessary interlocked to the appliance. Non Return Valves are included with the Lochinvar common flue header.
