*High Altitude Installations
I
nput ratings are shown in BTU per hour and are
certi
fi
ed without deration for elevations up to 4,500 feet
(1,370 m) above sea level.
For elevations above 4,500 feet (1,370 m) in USA,
installations must be in accordance with the current
ANSI Z223.1 and/or local codes having jurisdiction.
Heating value of gas in some areas is reduced to
compensate for elevation—consult your local gas utility
to con
fi
rm.
For installations at elevations above 4,500 feet (1,370
m) in Canada, please consult provincial and/or local
authorities having jurisdiction.
Supply Gas
Heater engine 738BXN is used with natural gas.
Heater engine 738BXP is used with propane gas.
The supply pressure must be between the limits shown
in the Ratings section above.
The supply connection is 3/8” NPT female and located
on the left hand side of the control valve. The gas line

Electrical
The 738 does not require an electrical power source to
operate as a heater.
Operating your
fi
replace for the
fi
rst time
When operating your new
fi
replace for the
fi
rst time,
some vapors may be released due to the burning of
curing compounds used in the manufacture of the
appliance. They may cause a slight odor and could
cause the
fl
ames to be the full height of the
fi
rebox, or
even slightly higher, for the
fi
rst few hours of operation.
It is also possible that these vapors could set off any
smoke detection alarms in the immediate vicinity.
These vapors are quite normal on new appliances. We
recommend opening a window to vent the room. After
a few hours use, the vapors will have disappeared and
the
fl
ames will be at their normal height.
