GENErAL INFOrMAtION
Note: Installation and repair should be per-
formed by a qualified service person. The appli-
ance should be inspected annually by a qualified
professional service technician. More frequent
inspections and cleanings may be required due
to yard care, insects, etc. It is imperative that
the control compartment and burners of the
appliance be kept clean.
Provide adequate clearances around air open-
ings and adequate accessibility clearance for
service and proper operation. Never obstruct
the front openings of the appliance.
these appliances are designed to operate on
natural or propane gas only.

Table 1
These appliances must be isolated from the
gas supply piping system (by closing their
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 (3.5 kPa).
These appliances and their individual shut-off
valves must be disconnected from the gas sup-
ply piping system during any pressure testing
of that system at pressures greater than 1/2
psig (3.5 kPa).
Orifice Sizes - Sea Level to High Altitude
(All Models)
These appliances are tested and approved for
installation at elevations of 0-4500 feet (0-1372
meters) above sea level, using the standard
burner orifice (See Table 4 ). For elevations
above 4500 feet, contact your gas supplier or
qualified service technician. Install the appli-
ance according to the regulations of the local
authorities having jurisdiction and, in the USA,
the National Fuel Gas Code NFPA 54 / ANSI
Z223.1 - latest edition or , in Canada, the CAN1-
B149.1 and .2 codes - latest edition.
