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 

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 
codes - latest edition.

       WARNING 

Failure to comply with the instal-
lation and operating instructions 
provided in this document will 
result in an improperly installed 
and operating appliance, voiding 
its warranty.  Any change to this 
appliance and/or its operating 
controls is dangerous.  Improper 
installation or use of this appli-
ance can cause serious injury or 
death from fi re, burns, explosion 
or carbon monoxide poisoning.

       WARNING 

Do not use these appliances if 
any part has been under water.  
Immediately call a qualifi ed, 
professional service technician 
to inspect the appliances and to 
replace any parts of the control 
system and any gas controls 
which have been under water.

     

WARNING

If the information in this 
manual is not followed 
exactly, a  fi re or explosion 
may result causing prop-
erty damage, personal 
injury or loss of life.

          IMPORTANT

These appliances must not be 
connected to a chimney or fl ue 
serving a separate solid fuel 
burning appliance. 

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).
