IMPORTANT INFORMATION
Do not use this burner system if any part has been
underwater. Immediately call a qualifi ed professional
service technician to inspect the appliance and to
replace any part of the control system and any gas
control which has been underwater.
The gas burner system must be isolated from the gas
supply piping system by closing its individual shut-off
valve during any pressure testing of the gas supply
system at test pressures equal to or less than
1
/
2
psig. The gas burner system and its individual shut-
off valve must be disconnected from the gas supply
piping system when testing at pressures in excess
of
1
/
2
psig.
Keep the area of the gas burner system clear and
free from combustible materials, gasoline, and other
fl ammable vapors and liquids.
Important: For safe operation and proper
performance and to comply
with CSA Certification, ONLY
Robert H. Peterson parts and
accessories must be used with
this gas burner system.
The minimum inlet gas supply pressure for purpose
of input adjustment is 5" for natural gas and 11" for
propane gas. Maximum inlet gas supply pressure for
this burner is 10.5" for natural and 13" for propane gas.
Gas supply pipe must be
1
/
2
" minimum interior diameter
or larger. If the gas line is longer than 20', a larger
diameter line may be necessary.
A fi replace screen must be in place when the
system is burning. Provisions for adequate
combustion air must be maintained. Unless other
provisions for combustion air are provided, the
screen shall have an opening(s) for introduction of
combustion air. Combustion air is adequate when
all fl ames curl into the fi replace and away from the
screen. When a glass fi replace enclosure (door) is
used, leave the doors fully open when the system
is in operation.
The minimum fi rebox dimensions in which the burner
system is certifi ed to be installed, is listed in the
Technical Data Table here.
Note: For remote ready units, the maximum
BTU thru put of some valves may vary.
Note: The minimum chimney height from hearth to top of chimney is 15'.
IMPORTANT
For all valves, the air MUST be purged from the gas line before the pilot will light and burn properly. The time
needed to purge will depend on the length of the gas line to the unit and the amount of time since the unit or gas
line was last used. It may take several minutes before all the air is purged and the pilot will light and burn properly.
Follow the LIGHTING INSTRUCTIONS section in this manual.
