WARNINGS
PRE-INSTALLATION AND PREPARATION SAFETY GUIDELINES
1. Before installing this unit, check the minimum clearance to combustible section
to ensure that the surrounding area is properly sized for the installation.
2. The unit is for outdoor use only. DO NOT install or use this appliance inside of
a building, garage, or any other enclosed area, including recreational vehicles
and/or boats. This unit must be installed in such a manner that the vent opening
at the base of the unit remains clear and free of all obstructions at all times
during all weather conditions.
3. CHECK GAS TYPE (natural or propane): the gas supply you intend to use may
not be the same as that stated on the unit rating plate as purchased. If the gas
supply is different, convert the unit to the gas type you intend to use. See the
CONVERTING TO A DIFFERENT GAS TYPE section. If you are unsure, contact
the dealer for assistance. ONLY MANUAL UNITS ARE CONVERTIBLE.
4. FOR NATURAL GAS: The minimum inlet gas-supply pressure for purposes of
input adjustments is 3.5” water column (w.c.), and the maximum inlet gas-supply
pressure is 10.5” w.c. FOR PROPANE: The minimum inlet gas supply pressure for
purposes of input adjustment is 8” w.c., and the maximum inlet gas supply 13”
w.c. DO NOT INSTALL THIS UNIT IF MINIMUM PRESSURE IS NOT AVAILABLE OR IF
MAXIMUM PRESSURE IS EXCEEDED.
5. Gas piping system must be sized to provide inlet pressure at the maximum flow
rate (BTU/hr). Undue pressure loss will occur if the pipe is too small, or the run is
too long.
6. For installations at elevations above 2,000 ft., contact your local dealer or gas
supplier before installing. Input ratings should be reduced approximately 4% for
each 1,000 ft. above sea level. Refer to the national Fuel Gas Code.
7. The unit and its individual shutoff valve must be disconnected from the
gas-supply piping system during any pressure testing of that system at test
pressures in excess of ½ psi (3.5 kPa). This is accomplished by closing the gas
supply line valve. The unit must be isolated from the gas supply piping system
by closing its individual manual shutoff valve during any pressure testing of the
gas-supply piping system at test pressures equal to or less than ½ psi (3.5 kPa).
8. INSTALLER NOTE: This unit should be installed so that it can be removed if
service is required.
9. GAS-SUPPLY PLUMBING REQUIREMENTS:
a. Apply only joint compounds that are resistant to all gases on all male pipe
fittings. Make sure to tighten every joint securely. Do not use pipe joint
compound to connect flare fittings. Bring the gas-supply pipe up from
beneath the enclosure near its center (if applicable).
Caution: Installation and maintenance must be done by an NFI Certified or other
qualified professional installer. Installer, read these instructions before installing this
product. Be sure you understand all safety precautions and warnings contained in this
manual.
Note:
An external on/off valve in the gas line is required for safety when the unit is not in use.
It also provides for convenient maintenance and repair.
