Burn-in period
During the first few fires of this appliance there
will be some odor due to the curing of the
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.

A white film may develop on the glass front
during the first few fires as part of the curing
process. The glass should be kept clean during
the first two weeks of use to prevent the film from
baking on (making it very difficult to remove).
See Glass Cleaning on Page 4.
Table 1 shows the units' gas orifice size for
the elevations indicated.
Maximum manifold pressure is 3.5 in. w.c. (0.87
kPa) for natural gas and 10 in. w.c. (2.49 kPa)
for LP/Propane gas.
Do not use these appliances if any part has
been under water. Immediately call a qualified,
professional service technician to inspect the
appliance and to replace any parts of the control
system and any gas control which have been
under water.
Ne pas se servir de cet appareil s'il a été plongé

Test gage connections are provided on the front
of the millivolt and electronic gas control valve
(identified OUT for the manifold side and IN for
inlet pressure. A 1/8" NPT test gage connection
is provided on the electronic gas control valve
adjacent to the outlet to the main burner.
Minimum inlet gas pressure to these appli-
ances is 5.0 inches water column (1.24 kPa)
for natural gas and 11 inches water column
(2.74 kPa) for propane for the purpose of input
adjustment.
Maximum inlet gas supply pressure to these
appliances is 10.5 inches water column (2.61
kPa) for natural gas and 13.0 inches water
column (3.23 kPa) for propane.
The appliance must be isolated from the gas
supply piping system (by closing its 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).
The appliance and its individual shut-off valve
must be disconnected from the gas supply
piping system during any pressure testing of
that system at pressures in excess of 1/2 psig
(3.5 kPa).
These appliances must not be connected to a
chimney or flue serving a separate solid fuel
burning appliance.
