Vent/Intake Pipe Connections To Blower/Air Duct - GSW 6G40NAV Mode D'emploi

Vent/Intake Pipe Connections To Blower/Air Duct

1. The plastic vent piping connects into the rubber
coupling located on the top of the blower assembly.
This coupling includes gear clamps to connect the
venting to the blower.
Important: These connections must be properly seated
and tightened to prevent the leakage of fl ue gases into the
area. See Figure 30 thru Figure 34.
2. The 40 and 50-gallon heaters with rated inputs of 45k
Btu/hr or less are designed and supplied with a 2"
rubber coupling to accept the vent pipe.
3. The 50 and 75-gallon models with rated inputs of 58k
Btu/hr or more are supplied with a 3" rubber coupling
to accept the vent pipe. Note: Polypropylene vent
systems require separate adaptor (fi eld supplied).
4. Before installing clean and lightly sand the end of the
PVC/CPVC plastic vent piping that will connect into
the rubber coupling. For polypropylene vent systems
follow manufacturer's instructions.
5. Loosen the upper clamp on the rubber coupling and
insert the sanded end of the vent piping a full 32mm (1-
1/4"). Do not use glue or sealant in the rubber coupling.
Check that there is no stress on the connection or the
vent piping that may be caused by twisting or bending.
6. Tighten the upper clamp so that the vent piping is
fi rmly secured in the coupling and is gas tight. Do not
over tighten or cause distortion of any of the parts.
Ensure the bottom of the rubber coupling is fi rmly
seated on the blower outlet and that the lower gear
clamp is also secure. Check to ensure there is no
distortion or movement of the clamped assembly once
it is completed.
CAUTION
Property Damage Hazard
• Do not overtighten the top and bottom gear clamps of the
rubber coupling.
• Do not apply solvent cement or silicone to the rubber
coupling connection.
