hook-up to gas supply
STEP 6:
HOOK-UP
A manual valve must be installed external to the
appliance, in an accessible location from the front
for the purpose of shutting off the gas supply. Make
sure the gas supply is turned off at the wall valve
before connecting the appliance. The gas supply
connections should be made by a qualified
technician and in accordance with local code or
ordinances. In the absence of a local code, the
installation must conform to the National Fuel
Gas Code ANSI 223.1-1988, latest edition.
To prepare the unit for connection to the gas
supply, thread the supplied 1/2” pipe nipple into
the elbow on the end of the manifold. The elbow is
located inside the chassis of the unit, on the end of
the manifold, facing down. See Fig. 9. It is accessible
through the square cutout in the left rear corner of the
chassis bottom. Connect the outlet of the regulator to
the exposed end of the nipple, connect the flex line from
the gas supply to the inlet side of the regulator.
CAUTION:
The appliance must be isolated from the building’s gas supply piping system by closing
its individual manual shut-off valve during any pressure testing of the gas supply piping
system at test pressures equal to or less than 1/2 psig (3.5kPa.) The appliance and its
individual shut-off valve must be disconnected from the gas supply piping system during
any pressure testing of the system at the test pressure in excess of 1/2 psig (3.5kPa.).
When checking the manifold gas pressure, the inlet pressure to the regulator should be at
least 7.0” W.C. for natural gas or 12.0” for LP.
NOTE: The arrow on the regulator indicating
direction of gas flow should be pointing towards
the unit. The flex line for the gas supply must be
metal and be approved by an approved certifying
agency (AGA, CGA, or UL.). Never use a hose
made of rubber or other synthetic material,
as the heat may cause the hose to melt and
develop leaks.
