flammable material on or near the heater. When
positioning the unit always maintain adequate
clearances around air openings into the
combustion chamber and allow for adequate
ventilation. Minimum clearances to combustibles
must be maintained as shown in Figures 5 - 8.
Note: The rear clearance to combustibles is
determined by either the unit’s or the vent pipe’s
minimum clearance, depending on whether the
installation calls for vertical rise within the room or a
rear exit, through-the-wall vent pipe. Ensure you
consider the need for access to the gas control valve
access door on the front of the unit as well as full
access for periodic cleaning and servicing. Also
consider clearance for the blower assembly if present,
or planned in the future
CAUTION: THESE CLEARANCES REPRESENT
MINIMUM DISTANCES IN ALL CASES, WHICH,

where it touches the wall. Use the center of this circle
as the center point of the 10” x 10” square wall pass
through.
Cut and frame the wall for the vent pipe. Install the
horizontal vent termination on the outside of the wall.
Ensure both of the retaining straps extend through the
wall pass through to the inside of the wall.
Before attaching the vent termination to the outside of
the house, run a bead of non-hardening mastic around
the outside edges, between the vent termination and
the wall. The arrow on the end cap should point up.
Secure the cap to the wall with the appropriate screws.
Put the adjustable (11”-14”) pipe into the horizontal
vent cap, (the vent pipe must extend into the horizontal
vent cap a minimum of 1 ¼”). Move the stove and vent
pipe into position, insert the adjustable (11”-14”) pipe
into the 90° elbow, twist lock it.
Secure the straps from the horizontal vent termination
to the interior pipe with two sheet metal screws,
keeping the screws as close to the wall thimble as

Gas Supply & Connections
Connection Location
The gas supply connection is made to the
Champlain’s gas control valve under the bottom right
center of the unit using a 3/8” male NPT fitting. The
supply line should be ½” diameter, or appropriately
sized to provide a sufficient gas supply to meet the
maximum demand of the unit without undue loss of
pressure. We recommend a flexible line to avoid
undue mechanical load on the valve and to ease
thread alignment, but refer to local codes.
The Champlain is factory equipped to use natural gas
(NG) and requires conversion for use with propane
(LP). A propane (LP) fuel conversion kit is included
with your stove purchase.
Gas Supply
This appliance and its individual shutoff valve must be
disconnected from the gas supply piping system
during any pressure testing of that system at test
pressures in excess of ½ psig. The Champlain must
be isolated from the gas supply piping system by
closing its individual manual shutoff valve during any
pressure testing of the gas supply piping system at
test pressures equal to or greater than ½ psig. Over
pressurizing can damage the control resulting in
leakage or control malfunction.
NOTICE: A QUALIFIED TECHNICIAN MUST
CONNECT THE HEATER TO THE GAS SUPPLY
AND LEAK TEST THE UNIT BEFORE IT IS
APPROVED FOR USE. CONSULT ALL CODES.
WARNING: THE UNIT MUST BE INSTALLED AND
CONNECTED IN ACCORDANCE WITH LOCAL
CODES, OR IN THE ABSENCE OF LOCAL CODES,
WITH THE MOST CURRENT EDITION OF THE
NATIONAL FUEL GAS CODE ANSI Z223.1 (NFPA
54) OR CAN/CGA B149 INSTALLATION CODE.
INSTALLER L'APPAREIL SELON LES CODES OU
RÈGLEMENTS LOCAUX, OU, EN L'ABSENCE DE
TELS RÈGLEMENTS, SELON LES CODES
D'INSTALLATION CAN/CGA-B149
NFPA Code and Hearthstone require the use of a
dedicated sediment trap just upstream of the unit.
Damage to the valve, or other components due to
the lack of a sediment trap are not covered by
warranty (see figure 17).
High Altitude Installations
For high altitude installations consult the local gas
distributer or the authority having jurisdiction for
proper rating methods.
The decreased atmospheric pressure at higher
altitudes affects the heat value of fuel gases. Gas
suppliers typically derate the gas intended for use at
elevations above 2000 feet (610 meters). This is not
necessary with the Champlain.

WARNINGS
•Fire or Explosion Hazard. Can cause property
damage, severe injury, or death. Do NOT bend
tubing at gas valve connection point after
compression fitting has been tightened. This
can result in gas leakage at the connection.
•Use new properly prepared pipe free from metal
or material chips. When tubing is used, assure
that ends are square, de-burred and clean. All
tubing bends must be smooth and free of
distortion.
•Do NOT over tighten connections.
Over tightening can damage the control body
resulting in leakage or control malfunction.
•Do NOT remove screws from the gas valve. Do
NOT adjust and/or alter any components
marked with tamper indicating paint. Motor
knob is not to be removed.
•Turn off gas supply at the appliance service
valve before starting installation, and perform a
Gas Leak Test after the installation is complete.
•Install the sediment trap (where required) in the
gas supply line to prevent contamination of the
gas valve (see figure 17).
•Use only your hand to push in or turn, the
gas Control knobs. Never use tools. If a
knob will not push in or turn by hand, do
NOT try to repair it. Call a qualified service
technician. Force or attempted repair will
void warranty and can result in a fire or
explosion.
GAS CONNECTIONS
Connection Main Gas (Tubing connections)
1. Do NOT use pipe joint compound or
Teflon®/PTFE tape.
2. Slip nut and ferrule over tubing.
3. Slide nut and ferrule into place, and insert
tubing into inlet/outlet connection until it
bottoms. Turn until finger-tight.
4. Use a wrench to tighten nut about 1 turn beyond
finger tight.
Connection Main Gas (Pipe Connections)
1. Do NOT use Teflon®/PTFE tape.
2. Pipe to be inserted into the valve must be the
proper thread length and to gauge. Thread
that IS cut too long can cause distortion or
malfunction if inserted too deeply.
3. Apply a moderate amount of approved
pipe\sealant to the pipe only, leaving the
two end threads bare.
4. Connect pipe to valve inlet and outlet.
Figure 17 –Sample Gas Supply Sediment Traps
PERFORM INITIAL GAS LEAK TEST
1. Check carefully for gas leaks immediately after
the appliance has been installed and the gas
turned on. Do this before attempting to operate
the appliance or other gas burning device.
1. Use an approved non-corrosive leak detection
fluid, or other approved leak detection method,
around the diaphragm flanges, pipe connections,
seal cap, and all other joints. Bubbles indicate a
leak.
2. If no leakage is detected, proceed with the
instructions listed on page 21 to light the main
burner and perform a secondary leak check of the
appliance gas supply system.
5. If a leak is detected, tighten pipe connections
(including adapters) according to "GAS
CONNECTIONS" (page 18).
