Attention: Do not remove the three marking plates (Rating Plate, Operation Instructions, Safety Plate) from the appliance.
Installing the Venting System
Use only manufacturer-approved venting components. Ensure unobstructed flow of combustion gases and ventilation air. Minimum clearance between pipes and combustible materials is 1" (25.4 mm). Vent terminal must be 18.0" from an adjacent wall. Minimum clearance between vent cap and combustible material is 1-3/4".
Venting System Components: A - Vent Cap, B - Vent Pipe, C - Vent-Air Intake Pipe, D - Rod, E - Nut, F - Outdoor Mounting Plate, G - Silicon-Rubber Ring, H - Tape, i - Insulation.
Pipe Lengths: Table 3 provides lengths for Vent Pipe (B), Vent-Air Intake Pipe (C), and Rod (D) based on wall thickness.
Installation Steps:
- Measure wall thickness. Trim pipes/insulation if necessary.
- Cut a 11-1/4" x 11-1/4" (286 mm x 286 mm) square hole through the wall (Figure 14).
- Screw the rod (D) slightly onto the appliance flue outlet.
- Wrap the vent-air intake pipe (C) with insulation (i) and secure with tape (H).
- Slide vent pipe (B) and intake pipe (C) through the wall hole and connect them to the appliance flue outlet and air intake.
- Install the outdoor mounting plate (F) and rubber ring (G) between the vent cap (A) and the exterior wall. Position the plate flush, seal with mastic, and ensure the intake pipe has a slight downward slope to the outside to prevent rainwater entry.
- Apply mastic around the vent cap (A) edge before attaching it to the outdoor mounting plate (F) (Figure 15).
- Slide the vent cap (A) into position and secure with nut (E) until it leans against the mounting plate (Figures 14 & 15).
Installing the Thermostat Sensor
To protect the sensor during shipping and handling, it is not attached at the factory. Once the heater is installed:
- Separate the front panel by removing the two bottom nuts and sliding it up (Figure 16).
- Place the thermostat sensor under the right bottom of the bracket and attach it with the provided medium screw (i) (Figures 17 & 18).
Gas Piping
Use new black iron or steel pipe. Ensure the gas supply line is sized correctly and provides sufficient gas flow without pressure loss. Use sealant resistant to L.P. Gas. The supply system must include a manual shutoff valve. Include a drip leg (trap) and a plugged 1/8" N.P.T. tapping for test gauge connections.
Pressure | |
---|---|
Nat. Gas | 7" W.C. to 10.5" W.C. |
Nat. Gas | 178 mm W.C. to 267 mm W.C. |
L.P. Gas | 11" W.C. to 14" W.C. |
L.P. Gas | 280 mm W.C. to 356 mm W.C. |
L.P. Gas Warning: Use a PRESSURE REGULATED gas supply. Do not connect the L.P. supply tank directly to the heater's pressure regulator. The tank must have its own regulator to reduce pressure to a maximum of 14 inches (355 mm) of water column.
