Orifi ce 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 "*" in Table 7). For
elevations above 4500 feet, contact your gas
supplier or qualifi ed service technician. 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
CAN1-B149.1 and .2 codes - latest edition.

Honeywell Millivolt Gas Valve
Electronic Models - Electronic models have a
fi xed rate gas valve. Input of electronic models
is shown in Table 3.
MASSACHUSETTS REQUIREMENTS
These appliances are approved for installation in
the following USA locations listed below:
Installation of these fi replaces are approved
for installation in the US state of Massachu-
setts if the following additional requirements
are met -
• Installation and repair must be done by a
plumber or gas fi tter licensed in the Com-
monwealth of Massachusetts.
• The fl exible gas line connector used shall not
exceed 36 inches (92 centimeters) in length.
• The individual manual shut-off must be a
T-handle type valve.

Table 5
Test gauge connections are provided on the
front of the millivolt gas control valve, identi-
fi ed IN for the inlet and OUT for the manifold
side. A 1/8" NPT Test gauge connection
is provided at the inlet and outlet side of
the electronic gas control valve.
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).
These appliances must be isolated from the gas
supply piping system (by closing their individual
manual shut-off valve) during any pressure test-
ing of gas supply piping system at test pressures
equal to or less than 1/2 psig (3.5 kPa).
