WARNING
Maintenance is required to maintain safe operation of the boiler.
The boiler must be inspected annually by a licensed professional. Repairs and maintenance shall be performed by a licensed professional. The licensed professional must verify proper operation after servicing.
Keep the boiler area clear and free from combustible materials, gasoline, and other flammable vapors and liquids.
To protect yourself from harm, before performing maintenance:
- Turn off the electrical power supply by unplugging the power cord or by turning off the electricity at the circuit breaker. (The boiler controller does not control the electrical power.)
- Turn off the gas at the manual gas control valve, usually located immediately below the boiler.
- Turn off the incoming water supply. This can be done at the isolation valve immediately below the boiler or by turning off the water supply to the building.
13.1 Owner Maintenance
WARNING
If you encounter a problem that is difficult to solve, stop the operation and immediately contact a licensed professional.
Table 49: MONTHLY
| Boiler Area | Piping | Venting | Boiler | |
|---|---|---|---|---|
| Verify the area is free of combustible materials, gasoline and other flammable vapors and liquids. Verify the area is clean from dust and obstructions. Verify the air intake area is free of any contaminants listed in the boiler Installation and Operation Manual. Any contaminants in the boiler intake air vicinity must be removed. If they cannot be removed, contact a licensed professional. | Inspect all water, gas, and condensation piping for leaks. Look for signs of leaking lines or corrosion. Confirm the condensation line is not blocked. If a condensation drain pump is used, confirm the condensation drain pump operates correctly. | Verify the boiler vent discharge and air intake is clean and free of obstructions. Check for leakage, damage, or deformation of venting. | Verify the boiler is free from any abnormal situations, such as diagnostic error codes, loud noises, leakage or other potential issues. Check that the pressure on the controller display or external pressure gauge indicates 17 to 26 PSI (117 to 180 kPa). |
Update #2:
The second update to the I-Series Plus Boiler Combi and Heat-Only Installation and Operation Manual applies to the two sections below:
- Section in Manual: 5.5.5 Non-Direct Vent (Room Air) Termination Clearances – Table 23, Reference B (Clearance to window or door that may be opened) (Figure 2).
- Section in Manual: 5.5.2 Direct Vent (Concentric and Twin Pipe) Termination Clearances – Table 15, Reference B (Clearance to window or door that may be opened) (Figure 3).
In both sections, Reference B for Canadian installations is being modified to reflect the new clearances as shown in the table below.
