GAS CONNECTIONS

Before connecting the appliance to the gas supply line, double check that the appliance you have
purchased is designed for the gas type you are using. The gas type markings are located on the
certification label and also on the appliance’s gas valve.

Adequate clearance for proper installation and checking of the gas connections must be provided. All

gas connections must be checked for gas leaks.

Have your gas supplier or a qualified gas fitter run a gas supply line into the fireplace. The line must
be properly sized and fitted according to the installation codes. Immediately upstream of the supply
connection, the fitter shall provide an accessible manual shut-off valve. When connecting the supply
line to the gas valve, the installer shall brace the gas valve to ensure that the gas valve is not moved
from its bracket. If the valve is not braced when the supply line is connected, the valve may be

moved and cause a “break” in the main burner supply line. Such damage is not covered by the
manufacturer’s warranty.

C A U T I O N

The 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 1/2 psig (3.5 kPa).
The appliance 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 less than 1/2 psig (3.5 kPa). Failure to do so will damage the appliance’s gas valve. Such damage

is not covered by the manufacturer’s warranty.

Natural Gas Pressure Settings:

The inlet supply or line pressure must be a minimum of 4.5” W.C. (1.2 kPa) and a maximum of 14”

W.C. (3.5 kPa). The orifice is a #33 DMS (2.87) drill size.

ELEVATION INPUT RATING
0-4500 ft (0-1372 M) 33,000 BTU/hr (9.6 kW)
4500 ft (1372 M) and above. 33,000 BTU/hr (9.6 kW) less 4% per 1000 ft. (305 M)
Please contact your local distributor for the appropriate orifice size you require.

Propane Pressure Settings:

The inlet supply or line pressure must be a minimum of 11” W.C. (2.8 kPa) and a maximum of 14”

W.C. (3.5 kPa). The orifice is a #51 DMS (1.73 mm) drill size.

ELEVATION INPUT RATING
0-4500 ft. (0-1372 M) 31,000 BTU/hr (9.02 kW)
4500 ft. (1372 M) and above. 31,000 BTU/hr (9.02 kW) less 4% per 1000 ft. (305 M)
Please contact your local distributor for the appropriate orifice size you require.

I N S T A L L E R S N O T E

THE INPUT RATING SHOULD BE CHECKED ON INITIAL START-UP OF THIS APPLIANCE.

To do this, reduce the background flow rate, time the meter.
Light the fireplace and take another reading after 15 minutes of operation.
Check with your gas supplier for the gas BTU content at your elevation.
Input is the rate of flow multiplied by the heating value of the gas (3600 x Calorific Value) divided by
the time (in seconds) it takes for (1) rotation of the 1 cubic foot dial on the meter.
Adjust the manifold pressure so that the unit does not operate above the rated input.

FINAL INSTALLATION CHECK

Each Archgard Gas Fireplace is checked and tested at the factory prior to being packaged and
shipped to our dealers and finally installed in your home. Archgard recommends that before leaving
this unit with the customer, the installer must ensure that the appliance is firing
correctly and that the electrical system is in working order. This will include:

1. Perform leak tests of supply line, gas control valve, supply line from gas control valve and pilot

assembly.

2. Clocking the appliance to ensure the correct firing rate (see page 9 of this manual).

3. If required, adjusting the primary air to burner to ensure that the flame does not carbon or soot.

4. Check for proper operation including correct drafting.

5. The fireplace should be turned ON for a sufficient time to ensure that the fan is working correctly.

After the system has been checked and confirmed that the fan is in working order, refer to the in­structions for FIRST FIRE located in this manual.

As a reminder, a TAG is attached to all of our gas fireplaces. This TAG is located at the gas control
valve. See Fig 1.

TROUBLESHOOTING

Please check to make sure the instructions are followed exactly before attempting
troubleshooting of the appliance.

W A R N I N G

Troubleshooting and servicing of gas and electrical devices of the appliance should only be

conducted by a qualified service technician.

SYMPTOM ACTION

Pilot will not light after pressing
the sparker many times.

1. When lighting the appliance for the first time after installation or after

servicing, there is air in the gas line. It takes a while for all of the air to
purge out of the pilot before gas can reach the pilot and ignite. Remove
the glass door and try lighting the pilot many times to purge the air.

2. Check to make sure the gas supply to the appliance is turned on and there

is adequate gas supply pressure to the appliance.

3. Check for sparks between the spark electrode and the pilot head when the
sparker is pressed. If there are no sparks:
a. Check for broken or poor connection from the sparker to the electrode.
b. Check for the spark shorting or arcing at other locations.
c. Check for defective sparker.
d. Check for defective spark electrode.

4. With the door removed, try lighting the pilot with a match.

a. If air is blowing on the flame of the match, hold the control knob in at the

‘PILOT’ setting until all the air is purged out of the line.

b. If there is no gas or air coming out of the pilot and there is gas pressure

to the appliance, the pilot orifice may be blocked or the gas valve may
be defective.

Pilot will not remain on after
being lit.

The main burner does not turn
on with the pilot lit.

1. Press the control knob all the way in (at the “pilot” indicator).

2. Hold the control knob in for a longer period of time.

3. If you are trying to re-light the pilot immediately after you have shut-off the

pilot, you have to wait 5 minutes for the valve to reset. (safety system built
into the valve)

4. Check to see if the pilot flame is large enough to reach and surround the

thermocouple. If the flame is too small, check for correct gas supply
pressure. If pressure is good, adjust the pilot flame size with the
adjustment screw on the valve. If the flame cannot be adjusted, there
might be some debris obstructing the pilot orifice, or a wrong size pilot
orifice.

5. Check for poor connection of the thermocouple to the valve.

6. Check for proper millivolts of the thermocouple. The thermocouple should
generate at least 20 mV or it is defective.

7. Check for defective gas valve.

1. Check to make sure the control knob is turned to the ‘ON’ position.

2. Allow enough time for the pilot to heat up the thermopile to generate suffi­cient voltage to activate the valve.

TROUBLESHOOTING Cont...

SYMPTOM ACTION

The main burner does not turn
on with the pilot lit. Cont...

The main burner shuts off when
the appliance is warm.

Sooty deposits on the glass
door.

3. Check to make sure the thermostat is set high enough to turn on the

appliance.

4. Check that the remote switch or the thermostat is turned on.

5. Check for weak pilot flame. If the flame is weak, check gas supply, check

pilot flame adjustment and check for blockage of pilot orifice.

6. Check all connections to the valve for tight electrical contact.

7. Check for 400-500 mV from the thermopile with the burner off and 185­250 mV with the burner on. If the voltages are lower, the thermopile is
defective.

8. Check for defective gas valve.

1. This may be the normal operation of a wall thermostat installed to appli­ances.

2. Check for good pilot flames on the thermopile.

3. Check for good voltage from the thermopile.

4. If venting is suspected, refer to the venting section of this manual for
proper venting practices.

5. Check wire connections. Expansion from heat affects a loose connection.

1. If the flame is yellow and lazy, check for lint etc. around primary air shut­ter. Increase primary air by opening the primary air shutter if necessary.

2. Check for proper placement of the logs and branches. Ensure logs and
burner are clean. See that section in the instruction manual.

3. Check for proper venting and blockage of the vent termination.

4. Check manifold pressure and clock input rating for over-firing.

Sharp blue flames with flames
lifting off the burner at the ends.

Convection blower does not turn
on.

1. Too much primary air. Reduce primary air by closing the primary air

shutter. During cold temperatures, some flame lifting may occur during
start-up.

1. The convection fan is thermostatically controlled. It will only turn on when

the appliance is warmed-up. This may take up to 15 minutes with the
appliance on high.

2. Check for 120 VAC electrical supply to the appliance. (Is the cord
plugged in?)

3. Check for proper mounting of the thermal snap disc.

4. Check electrical connections.

5. Check for defective thermal snap disc.

6. Check for defective convection blower speed controller.

7. Check for defective convection blower.

FREQUENTLY ASKED QUESTIONS

Listed below are some frequently asked questions regarding Archgard Gas Fireplaces. If you have
questions that are not listed below, or are not answered in this manual, please contact your Author­ized Archgard Dealer.

Q. My glass has a condensation “fog” when the appliance is first lit.
A. Condensation is normal and will disappear in a few minutes after the glass is heated.

Q. I have a white “film” on my glass. What is the best way to clean the inside of the glass.
A. Frequent cleaning of your glass is recommended. Archgard recommends using a good quality

“gas fireplace” glass cleaner that is available at all authorized dealers. Do not use abrasive materials,

and do not clean the glass or the appliance when the unit is hot.

Q. How do I care for my plated trims.
A. Archgard recommends a cleaning with a damp cloth. DO NOT use chemical cleaners as they may

harm the finish, and void your warranty. NOTE: If the top louvers, or top overlay starts to discolor,
check the door gasket seal and replace if necessary.

Q. My fan/blower makes a “whirring” or “humming” noise.
A. Your Archgard gas appliance uses a powerful fan to push heated air into your room. It is not un-

usual to hear a “humming” noise when your fan is running. Note: the sound will change depending on

the setting that your fan speed control is set at.

Q. I hear a “click” when my fan system activates.
A. When your appliance reaches temperature, it will activate the THERMODISC “fan switch”. The

switch closes the electrical circuit that allows the fan to turn on. This is a normal sound.

Q. I hear a “ticking”, “cracking” or “pinging” sound when my fireplace is running, and after it is turned

off.
A. The different gauges of steel used to manufacture your fireplace will expand and contract at differ­ent rates when your fireplace is on, and will continued as your fireplace completes its heating func­tion. You will likely hear these same sounds more on start up and shut down. This is normal for steel
fireplaces.

Q. I hear a “click" when my main burner turns ON or OFF.
A. Your Gas Control Valve will make a clicking sound when it opens to allow gas to flow to the main

burner. This is a normal part of the operating system.

Q. Can I burn wood and other materials in my gas fireplace.
A. No! Burning anything other than natural or LP gas in a gas fireplace or stove will create a potential

fire hazard and present a danger to your home and its occupants. Only burn the gas fuel for which
the unit was originally designed.

Q. Can I shut my pilot off in the summer?
A. You will save energy by turning off the pilot light if you are not using your appliance for the hot

summer months. Remember to relight it before you want to use the appliance for the first time in the
fall. Refer to your owners manual for lighting instructions.

Q. Can I position my gas logs in a different fashion or use a different log set?
A. No. Your gas fireplace is an engineered system that includes the firebox, burner, logs, venting and

options which are tested and listed by CSA. Changing any specifications or placement of the logs
could void your manufacturer's warranty, and possible even your homeowner's warranty.
