IMPORTANT:
PLEASE REVIEW THE FOLLOWING CAREFULLY
Remove any plastic from from parts before turning the
unit ON.
It is normal for stoves fabricated of steel to give off some
expansion and/or contraction noises during the start up
or cool down cycle. Similar noises are found with your
furnace heat exchanger or car engine.
It is not unusual for your gas stove to give off some odor
the first time it is burned. This is due to the curing of the
paint and any undetected oil from the manufacturing
process.
Please ensure that your room is well ventilated-open
all windows.
It is recommended that you burn your stove for at least
ten (10) hours the first time you use it. If the optional fan

There is a minimum vertical rise required
for the venting, which varies depending on
the application. The maximum horizontal
run also has restrictions. Before starting
the installation, become familiar with venting instructions starting on Page 9.
Clearance to Combustibles
The use of wallpaper adjacent to this stove is not recommended, as the high heat given off by this stove may
adversely affect the binders in the adhesive used to
apply the wallpaper.
Before beginning, remove the window frame assembly
from the stove. Also check to make sure there is not
hidden damage to the stove. Take a minute and plan
out the gas, vent and electrical supply. Refer to Window
Frame Assembly Removal Section.

Vent Pipe................................................ 1” (25 mm) The gas pipeline can be brought in through the rear of
the stove as well as the bottom. Knockouts are provided
on the bottom behind the valve to allow for the gas pipe
installation and testing of any gas connection. It is most
convenient to bring the gas line in from the rear right
side of the valve as this allows fan installation or removal without disconnecting the gas line.
High Elevations
The gas line connection can be made with properly
tinned 3/8” copper tubing, 3/8” rigid pipe or an approved flex connector. Since some municipalities have
additional local codes, it is always best to consult your
local authority and the National Fuel Gas Code, ANSI
Z223.1/NFPA 54 in the USA or the CSA-B149.1 installation codes.
Input ratings are shown in BTU per hour and are
certified 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/NFPA 54 and/or local codes having jurisdiction.
In Canada, please consult provincial and/or local
authorities having jurisdiction for installations at
elevations above 4,500 feet (1,370 m).

open flame for leak testing.
The gas control is equipped with a captured screw type
pressure test point, therefore it is not necessary to provide a 1/8” test point up stream of the control.
When using copper or flex connector use only approved
fittings. Always provide a union when using black iron
pipe so that the gas line can be easily disconnected for
burner or fan servicing . See gas specifications for pressure details and ratings.
The stove valve must not be subjected to any test pressures exceeding 1/2 psi. Isolate or disconnect this or
any other gas appliance control from the gas line when
pressure testing.

General Information on Assembling Vent Pipes
Canadian Installations:
The venting system must be installed in accordance
with the current CSA-B149 .1 installation code.
USA Installations:
The venting system must conform with local codes and/
or the current National Fuel Gas code ANSI Z223.1/
NFPA 54.
Only venting components manufactured by MHSC can
be used in Direct Vent systems.
To join the twist lock pipes together, simply align the
beads of the male end with the grooves of the female
end, then while bringing the ends together, twist the
pipe until the flange on the female end contacts the
external flange on the male end. It is recommended that
you secure the joints with three (3) sheet metal screws,
however this is not mandatory with twist lock pipe.
To make it easier to assemble the joints we suggest
putting a lubricant (Vaseline or similar) on the male end
of the twist lock pipe prior to assembly.
Twist Lock Pipes
When using MHSC twist-lock pipe it is not necessary to
use sealant on the joints. The only areas of the venting
system that need to be sealed with high temperature
silicone sealant are the collars on the stove and termination, and the sliding joint of any telescopic vent section used in the system.

How to Use the Vent Graph
Vertical Sidewall Applications
The vent chart should be read in conjunction with the
following vent installation instructions to determine the
relationship of the vertical and horizontal dimensions of
the vent system.
1. Determine the height of the center of the horizontal vent pipe exiting through the outer wall. Using
this dimension on the Sidewall Vent Graph (Fig. 8),
locate the point intersecting with the slanted graph
line.
2. From the point of this intersection, draw a vertical
line to the bottom of the graph.
3. Select the indicated dimension, and position the
stove in accordance with same.
Example A:
If the vertical dimension from the floor of the unit is 11’
(3.4m) the horizontal run to the face of the outer wall
must not exceed 14’ (4.3 m).
Example B:
If the vertical dimension from the floor of the unit is 7’
(2.14m), the horizontal run to the face of the outer wall
must not exceed 8¹⁄₂’ (2.6 m).
30
Since it is very important that the venting system maintain its balance between
the combustion air intake and the flue
gas exhaust, certain limitations as to vent
configurations apply and must be strictly
adhered to.
The vent graph showing the relationship between vertical and horizontal side wall venting will help to determine the various dimensions allowable.
Minimum clearance between vent pipes
and combustible materials is one 1”
(25mm) on top, bottom and sides unless
otherwise noted.
When the vent termination exits through foundations
less than 20” (508 mm) below siding outcrop, the vent
pipe must flush up with the siding.
It is always best to locate the stove in such a way that
minimizes the number of offsets and horizontal vent
length of vent pipe from the flue collar of the stove to
the face of the outer wall.
Horizontal plane means no vertical rise exists on this
portion of the vent assembly.
• The maximum number of 90° elbows per side wall
29
installations is three (3).

Locate vent opening on the wall. It may be necessary
to first position the stove and measure to obtain hole
location. Depending on whether the wall is combustible
or noncombustible, cut opening to size. (Fig. 13)
For combustible walls first frame in opening.
Combustible Walls: (Fig. 13) Cut a 9³⁄₈”H x 9³⁄₈”W (240
x 240 mm) hole through the exterior wall and frame as
shown.
Noncombustible Walls: (Fig. 13) Hole opening must

NOTE: If using charcoal wall plate Pt. #10000257,
and collar Pt. # 52203-CG, put them in place before
putting the pipe sections through the wall.
Use appropriate length of pipe sections - telescopic or
fixed - and install the horizontal vent sections. The sections which go through the wall are packaged with the
starter kit, and can be cut to suit if necessary. (Fig. 18)
Sealing vent pipe and firestop gaps with
high temperature sealant will restrict cold
air being drawn in around stove.

Below Grade Installations
When it is not possible to meet the required vent terminal clearances of 12” (305 mm) above grade level a
snorkel vent kit is recommended. It allows installation
depth of down to 7” (178 mm) below grade level. The
7” is measured from the center of the horizontal vent
pipe as it penetrates through the wall.
If venting system is installed below
ground, we recommend a window well with
adequate and proper drainage.
Ensure sidewall venting clearances are
observed.
FP1511
Fig. 18 Pipe sections through the wall.
STEP 7
Apply high temperature sealant to 4” (102 mm) and
7” (179 mm) collars or the termination one inch away
from crimped end. Guide the vent terminations 4” and
7” collars into their respective vent pipes. Double check
that the vent pipes overlap the collars by 2” (51 mm).
Secure the termination to the wall with screws provided
and caulk around the wall plate to weatherproof. (Fig.
19)
If installing a snorkel, a minimum 24” (610 mm) vertical
rise is necessary. The maximum horizontal run with
the 24” (610 mm) vertical pipe is 36” (914 mm). This
measurement is taken from the collar of the stove (or
transition elbow) to the face of the exterior wall. Refer to
the Sidewall Vent Graph for extended horizontal run if
the vertical rise exceeds 24” (610 mm).
1. Establish vent hole through the wall. (Fig. 13)
2. Remove soil to a depth of approximately 16”
(406 mm) below base of snorkel. Install drain pipe.
Install window well (not supplied). Refill hole with 12”
(305 mm) of coarse gravel leaving a clearance of
approximately 4” (102 mm) below snorkel. (Fig. 20)
3. Install vent system.
4. Ensure a watertight seal is made around the vent
pipe coming through the wall.
5. Apply high temperature sealant caulking (supplied)
around the 4” and 7“ snorkel collars.
6. Slide the snorkel into the vent pipes and secure to
the wall.
7. Level the soil to maintain a 4” (102 mm) clearance
below snorkel. (Fig. 20)

Glass Cleaning
It is necessary to periodically clean the glass. During
start-up condensation, which is normal, forms on the
inside of the glass. This condensation causes lint, dust
and other airborne particles to cling to the glass surface.
Also initial paint curing may deposit a slight film on
the glass. It is therefore recommended that the glass
be cleaned two or three times with a non-ammonia
based household cleaner and warm water (We
recommend gas stove glass cleaner) within the first
few weeks of operation.

With the control knob in the pilot position, push the
control knob all the way and hold. Check for spark at
electrode and pilot. If no spark to pilot, and electrode
wire is properly connected, replace the battery in the
ignitor module and try again. Refer to Maintenance
Section. If the problem still exists, replace the ignitor
module box.
A. Defective pilot generator (thermocouple), remote wall switch
Check pilot flame. Must impinge on thermocouple/thermopile. NOTE: This pilot burner assembly utilizes both
a thermocouple and a thermopile. The thermocouple
operates the main valve operation (On and Off). Clean
and or adjust pilot for maximum flame impingement on
thermopile and thermocouple.
B. Defective automatic valve
Turn valve knob to “Pilot”. Maintain flow to pilot; millivolt
meter should read greater than 10mV. If the reading
is okay and the pilot does not stay on, replace the gas
valve. NOTE: An interrupter block (not supplied) must
be used to conduct this test.
A. Wall switch or wires defective
Check wall switch and wires for proper connections.
Jumper wire across terminals at wall switch, if burner
comes on, replace defective wall switch.. If okay,
jumper wires across wall switch wires at valve, if burner
comes on, wires are faulty or connections are bad.
B. Thermopile may not be generating sufficient millivoltage
1. Be sure wire connections form thermopile at gas
valve terminals are tight and thermopile is fully
inserted into pilot bracket.
2. One of the wall switch wires may be grounded. Remove wall switch wires form valve terminals if pilot
now stays lit, trace wall switch wiring for ground.
May be grounded to fireplace or gas supply.
3. Check thermopile with millivolt meter. Take reading
at thermopile terminals of gas valve. Should read
250-300 millivolts (minimum 150) while holding
valve knob depressed in pilot position and wall
switch “Off”. Replace faulty thermopile if reading is
below specified minimum.
C. Plugged burner orifice
Check burner orifices for debris and remove.
D. Defective automatic valve operator
Turn valve knob to “On”, place wall switch to “On”
millivolt meter should read greater than 150mV. If the
reading is okay and the burner does not come on,
replace the gas valve.
A. Pilot flame may be too low or
blowing (high) causing the pilot
safety to drop out
Clean and/or adjust pilot flame for maximum flame
impingement on thermopile and thermocouple.
B. Possible blockage of the vent
terminal
Check the vent terminal for blockage (recycling the flue
gases).

Maintenance
Burner and Burner Compartment
It is important to keep the burner and the burner
compartment clean. At least once per year the logs and
lava rock/ember material should be removed and the
burner compartment vacuumed and wiped out. Remove
and refit the logs as per the instructions in this manual.
Always handle the logs with care as they
are fragile and may also be hot if the stove
has been in use.
To obtain proper operation, it is imperative that the pilot
and burner’s flame characteristics are steady, not lifting
or floating.
Typically, the top 3/8” to 1/2” of the thermopile should
be engulfed in the pilot flame. (Refer to Page 19, Figure
30)
To adjust pilot burner: (by qualified service technician)
1. Remove pilot adjustment cap
2. Adjust pilot screw to provide properly sized flame.
FK24 Fan Assembly
3. Replace pilot adjustment cap.
The fan unit requires periodic cleaning. At least once
per month in the operating season open the lower
louvre panels and wipe or vacuum the area around the
fan to remove any build up of dust or lint.
The primary air shutter is set at factory and should
only be adjusted, if necessary, by a qualified service
technician.
Brass Trim
Clean the brass trim pieces using a soft cloth lightly
dampened with lemon oil. Do not use water or
household cleaners on any brass components.
Cleaning the Standing
Pilot Control System
The burner and control system consist of:
•burner tube
•gas orifice
•pilot assembly •thermopile
•millivolt gas valve
Most of these components may require only an
occasional checkup and cleaning and some may
require adjustment. If repair is necessary, it should
be performed by a qualified technician.
1. Turn off pilot light at gas valve.
2. Allow stove to cool if it has been operating.
3. Remove window frame assembly. (Refer to Window
