LEG INSTALLATION
Installation of Banking Plates
All units may be installed independently or banked with
other GD or ED Series equipment. To ensure a matching
and permanent fit between units, two banking plates are
available for each unit to be installed. One at the front and
one at the rear of each two units being banked together.
1. Level each unit by adjustment of leveling bolts or legs.
Use a spirit level and level unit four ways; across front and
back and down left and right edges. Level all other units
to the first unit.
Gas Connections
1. The installation and connection must comply with local
codes, or in the absence of local codes, with CAN/CGA-
B149 Installation Code or with the national Fuel Gas Code,
ANSI Z223.1/NFPA No. 54 – Latest Edition.
2. The correct type of gas for which the unit was
manufactured is noted on the rating plate, and this type
of gas must be used.
3. The gas pressure must be checked when the unit is
installed, to ensure that the unit gas pressure is the same
as specified on the rating plate. If necessary, pressure
adjustments can be made at the pressure regulator,
supplied on each unit.
4. Have a qualified gas technician check the gas pressure
to make certain that existing gas facilities (meter, piping,
etc.) will deliver the BTU’s of gas required at the unit with
no more than ½” water column pressure drop. When
checking pressure, be certain that all the equipment on
same gas line is turned to the “ON” position.
5. The appliance and its individual shut off valve must be
disconnected from the gas supply piping system during
any pressure testing of that system at test pressures in
excess of 1/2 PSIG. (3.45 KPA).
6. The appliance must be isolated from the 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.
(3.45 KPA).
7. Make certain that the new piping, joints and connections
have been made in a clean manner and have been
purged, so that the piping compound, chips, etc., will not
clog pilots, valves and/or controls. Use pipe joint sealant
that is certified for use with liquefied petroleum gas.
8. WARNING: Check gas connections for leaks, using soap
solution or similar means. Do Not Check with an Open
Flame.
