1. as Pressure
or natural gas, the minimum inlet gas supply
pressure is 4.5 inches water column, and the
maximum inlet gas pressure is 7.0 inches water
column, for the purpose of input adjustment. Input rate
is 25,000 BTU/hr. or propane gas, the inlet gas supply
pressure must be at least 11.0 inches water column and
a maximum 14.0 inches water column.
Pressure taps are provided on the gas control valve,
near the outlet to the main burner immediately
upstream of the gas supply connection to the
appliance, accessible for a test gage connection.
Optimum manifold pressure is 3.5 inches water column
for natural gas, and 10.0 inches water column for
propane gas.
2. High Altitude Installation
a. U.S. Installation
Appliances are tested and approved for elevations
from 0-2000 feet.
When installing this appliance at an elevation above
2000 feet, United States codes require a decrease
of the input rating by changing the existing burner
orifice.
Input should be reduced 4% for each 1000 feet
above sea level. Check with the local gas utility for
proper orifice size identification. This appliance
uses a .096 in./2.44 mm. orifice size on natural gas
versions and a .059 in./1.49 mm. orifice size on
propane gas versions.
Consult your local gas company for assistance in
determining the proper orifice for your location or
refer to ANSI Z223. -latest edition, Appendix F.
b. Canadian Installation
Appliances are certified for elevations from 0-4500
feet. When installing this appliance at an elevation
between 0-4500 feet in Canada, the input rating does
not need to be reduced.
When installing this appliance at an elevation above
4500 feet in Canada, check with local authorities.
Consult your local gas company for assistance in
determining the proper orifice for you location or refer
to ANSI Z23. -latest edition, Appendix F.
3. Location and Space Requirements
This appliance may be installed along a wall, across a
corner or in an exterior chase. This appliance must be
installed so that the draft hood is in the same
atmospheric pressure zone as the combustion air inlet
and the appliance shall be located so that the relief
opening is accessible for checking vent operation. The
G136 Series may be installed at a height level with the
floor, or it can be raised up from the floor to enhance
its visual impact. igure 1 illustrates a variety of ways
the appliance may be located in a room. These
appliances are also certified for installation in a
bedroom or bed/sitting room in the U.S. and Canada
(bedroom installations in Canada require the addition
of non-operable doors), provided that the bedroom or
bed/sitting room has a volume of at least 1,250 cubic
feet.
WARNING!
To prevent contact with sagging or loose insu-
lation, the appliance must not be installed
against vapor barriers or exposed insulation.
