VENT PIPE
DRAFTHOOD
Figure 8. Vent Piping Requirements
The weight of the vent stack or chimney must not rest on
heater drafthood. Support must be provided in compliance
with applicable codes. The heater top and drafthood must
be readily removable for maintenance and inspection.
Vent pipe should be adequately supported to maintain
proper clearances from combustible construction.
Type "B" double-wall or equivalent vent pipe is
recommended. However single-wall metal vent pipe may
be used as specified in the latest edition of the National
Flue Gas Code ANSI Z223.1 (Canada - CAN/CSA-B149).

4.7. Gas Connections

Gas piping must have a sediment trap ahead of the heater
gas controls, and a manual shut-off valve located outside
the heater jacket. Use the pipe finish flange to seal
between the gas line and the heater jacket. See Figure
9. All gas piping should be tested after installation in
accordance with local codes.
CAUTION: Do not use 5, 10 or 20 gallon (19.38 to 76
A
Liter) propane tanks, like those used with consumer
barbecues, to supply gas to this heater.
CAUTION: The heater and its manual shut-off valve
A
must be disconnected from the gas supply during any
pressure testing of that system at test pressures in excess
of 1/2 psig (3.5 kPa). The heater and its gas connections
shall be leak tested before placing the appliance in
operation. Use soapy water for leak test. Do not use open
flame.

end threads bare.
4.7.1. Gas Pressure Regulator
The gas pressure regulator is preset at 4" W.C. (1.0kPa) for
natural gas and 10" W.C. (2.5kPa) for propane gas.
If adjustment is needed, remove plug and turn adjustment
screw clockwise to increase pressure or counter-
clockwise to decrease pressure.
