Burn-in Period
During the fi rst few fi res of this appliance
there will be some odor due to the curing of
paint and burning off of lubricants used in the
manufacturing process.
Depending on your use, the burn-in period may
take a few hours or a few days.
Test gauge connections are provided on the front
of the millivolt gas control valve, identifi ed IN for
the inlet and OUT for the manifold side (see Fig-
urex 2 on Pagex 4 ). A 1/8" NPT Test gauge con-
nection is provided at the inlet and outlet side of
the electronic gas control valve (see Figurex
3 on Pagex 5).
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 testing of the gas supply piping
system at test pressures equal to or less than
1/2 psig (3.5 kPa).
Orifi ce Sizes - Sea Level to High Altitude
(All Models)
These appliances are tested and approved for
installations at elevations of 0-4500 feet (0-1372
meters) above sea level using the standard burner
orifice sizes (marked with an "*" in Table 6 ).
For elevations above 4500 feet, these appliances
must be properly "derated" by the gas supplier
or qualifi ed service technician (usually done at
the time of installation).
Note: Derated (defi nition) - Replacing burner
orifi ce with a smaller one to reduce BTU input.
The installation of this appliance must be accord-
ing 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

KEEP YOUR HOUSE WELL VENTILATED
DURING THE CURING PROCESS. THE ODOR
AND HAZE EMITTED BY THE CURING PROCESS
CAN BE QUITE NOTICEABLE AND MAY SET OFF
A SMOKE DETECTOR.
A white fi lm may develop on the glass front
during the fi rst few fi res as part of the curing
process. The glass should be kept clean during
the fi rst two weeks of use to prevent the fi lm from
baking on (making it very diffi cult to remove).
See Glass Cleaning on Page 8.
