Test gauge connections are provided on the
front of the gas control valve, identified IN for
the inlet and OUT for the manifold side (see
Figures 1 and 2).
Propane tanks are at pressures that will cause
damage to valve components. Verify that the
tanks have step-down regulators to reduce the
pressure to safe levels.

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 sizes (marked with an asterisk
(*) in Table 4, below).
For elevations above 4500 feet, contact your
gas supplier or a qualified service technician.
deration
At higher elevations, the amount of BTU fuel
value delivered must be reduced by either:
• using gas that has been derated by the gas
company,
• changing the burner orifice to a smaller size
as regulated by the local authorities having
jurisdiction and by the (USA) National Fuel Gas
Code NFPA 54/ANSI Z223.1 - latest edition or,
in Canada, the CAN/CSA-B149.1 codes - latest
edition.
Install the appliance 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 CAN/CSA-B149.1 - latest edition.
NOTE: Flame appearance will diminish
4% per thousand feet of altitude.

GAS PRESSURE REqUIREMENTS
(All Models)
Tables 2 and 3 show the appliances' inlet and
manifold gas pressure requirements:
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 supply piping system
during any pressure testing of that
system at pressures greater than 1/2
psig (3.5 kPa).
