PRE-INSTALLATION AND PREPARATION SAFETY GUIDELINES
1. Before installing this unit, check the minimum clearance to combustibles 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 and during all weather
conditions.
3. CHECK GAS T YPE (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 T YPE 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
adjustment 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 B"w.c., and the maximum inlet gas-supply pressure is 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 minimum 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 sstem at test pressures in excess of½
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 than½ 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 gasses 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.
