Fig. 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 sup-
ported to maintain proper clearances from combustible
construction.
Type "B" double-wall or equivalent vent pipe is recom-
mended. 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/CGA-
B149).
Gas Connections
Gas piping must have a sediment trap ahead of the
heater gas controls, and a manual shut-off valve locat-
ed outside the heater jacket. All gas piping should be
tested after installation in accordance with local codes.
CAUTION: Do not use 5, 10 or 20 gallon propane
tanks, like those used with consumer bar-b-ques, to
supply gas to this heater.
CAUTION: The heater and its manual shut-off
valve 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.
