FIREPLACE INSTALLATION INSTRUCTIONS

It is important that you choose a location for your fireplace that will allow you to

install the vent and termination according to the venting and termination

specifications. Provide adequate accessibility clearances for servicing and

proper operation.

1. Once the final location of the fireplace has been selected, determine the

height and location of the vent terminal. Proper height in the vent system

provides for adequate combustion and ventilation air. See venting page 6.

2. Frame an opening in the outside wall 10’, wide by 12” high. The

minimum height to the center of this opening is 37” above the floor of

the fireplace. Before locating the fireplace, clean the area you have

selected.

3. Place fireplace in its final location and fasten the nailing flanges to the

framing.

4. When connecting gas line, provide a 1/8” NPT. pressure tap immediately up

stream from the gas supply connection.

5. 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 psi (3.5kPa).

VENTING INSTALLATION

NOTE: Use venting components and termination supplied by the Archgard. Exhaust (inner) vent is 4”

aluminum flex and intake (outer) vent is either aluminum flex or rigid 7” pipe.

1 Apply an even bead of approved high temperature sealant to the outside crimped area of the 4” fireplace

vent connector. Install 4” inner vent section or elbow to 4” vent connector on fireplace. Seal all the joints

with approved high temperature sealant and secure with three sheet metal screws.

2 Apply an even bead of approved high temperature sealant to the outside crimped area of the 7” fireplace

vent connector. Install 7” vent / elbow over the 4” section and secure to the 7” fireplace vent connector

with three sheet metal screws. The high temperature sealant should

be pressed firmly into all joints of the venting system to ensure seal.

3 Continue connecting and sealing vent sections until the vent is

centered in the framed opening and the 7” flexible vent is through the

exterior wall. The 4” vent should extend 2” beyond the 7” vent. Apply a

bead of approved high temperature sealant to the outside of the

terminal cap vent connectors and secure the flexible vents

to the collars of the vent terminal with sheet metal screws.

4 A minimum overlap of 1” is required on all vent connections.

Now you can push the terminal cap and vent back into the wall

until the terminal rests securely against the outside wall.

5 Lag the terminal cap to the wall using the four screws provided.

6 To ensure the 4” vent remains centered in the 7” vent, use vent

spacers springs provided at intervals along both the horizontal &

vertical sections of vent.

8 Horizontal sections of vent exceeding three feet in length shall be

supported by means of steel strapping, at three foot intervals.

For best and safe venting performance, here are some general venting rules:

1. Maintain a minimum of 1” (26 mm) clearance to combustibles from the outside surfaces of vertical vents and

min. 1” (26 mm) sides and bottom, and 2” (51 mm) from top surfaces of horizontal vents.

2. Observe the venting chart given in this manual.

3. Use vent spacers between the inside 4” and outside 7” vents at 3 ft (915 mm) intervals and at each change

of direction.

4. Never slope horizontal vents downwards, towards the vent termination.

5. Maintain a minimum 1/4” rise (7 mm) for every linear foot (305 mm) of horizontal vent. Support

horizontal vents every 3 ft (915 mm) to prevent sagging.

VENTING ROUTES AND COMPONENTS

Since it is very important that the vent 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. Fig. 5 shows the relationship between

vertical and horizontal ventings and shows maximum vent

lengths. The maximum horizontal vent run with 90 degree

elbow attached to the fireplace flue outlet is three feet (Fig.

5). The maximum number of 90 degree elbows per

installation is one. In addition the maximum number of 45

degree elbows per installation is two. This elbow can be

installed in either the vertical or horizontal run.

Special Note: For each 45 degree elbow installed in the

horizontal run, the length of the horizontal run must be

reduced by 18”. This does not apply if the 45 degree elbows

are installed on the vertical part of the vent system.

Example: If the length of the horizontal run is 10 feet, and

two 45 degree elbows are required, the horizontal run length

must be reduced to 7 feet.

Important: It is always best to locate the fireplace in such a

way that a minimum of offsets and / or horizontal runs are

required.

Note: The vent terminal should not be recessed into a wall or siding

Note: This gas appliance must

not be connected to a chimney

flue serving a separate solid-

fuel burning appliance.

GLASS / FRAME ASSEMBLY REMOVAL

1 Remove upper and lower grille assemblies by lifting and then pulling them straight out.

2 Release the glass frame clamps, located on the bottom of the firebox.

3 Then lift the glass frame out until the lower retainer clips are clear of the bottom edge of the

firebox, approximately 1 inch, and and then lift the door frame off, clear of the unit.

GLASS / FRAME ASSEMBLY INSTALLATION

1 With the upper and lower grille assemblies removed, hook the glass frame’s upper onto the

firebox.

2 Swing the bottom of the glass frame under the bottom edge of the firebox. Be certain that

the firebox is in full contact with the glass frame gasket.

3 Hook the bottom of the glass frame clamps onto the glass frame hooks.

4 Install both upper and lower grille assemblies.

! CAUTION !

The glass frame clamps have been factory adjusted and should not require further

adjustment. However, if the clamp tension appears to be too tight or too loose, have it

checked by a dealer or manufacturers representative.

Should the glass become damaged or broken, the glass and frame assembly should be

replaced as a complete unit as supplied by the manufacturer.

3 Place the front log on the burner. Ensure that the locating pins

on the burner are fully engaged with the locating holes on the

bottom of the front log and make sure the cut out on the

bottom of this log is aligned with the burner ports.

4 Place the top logs (left and right) into the locating indents on

the top of the front and rear logs.

5 Distribute the glowing ember material evenly across the front

of the burner only and in front of the log. They should be

pulled apart in dime size pieces and spread loose. Never

press glowing ember material into place.

LIGHTING AND OPERATING

This fireplace is equipped with a Nova SIT or Honeywell gas control valve.

The lighting and operating instructions will work on either valve type.

1 To light the pilot burner, turn the “on-pilot-off” knob on the control valve to the “pilot” position then

depress fully and hold.

2 Press the spark igniter until it makes a snapping sound. Repeat until pilot burner ignites. If the pilot

burner fails to ignite after 30 seconds, release the knob and turn to the “off” position.

3 Wait for 5 minutes and repeat the process.

4 When the pilot burner ignites continue to hold the control valve knob depressed for about 30 sec-

onds.

5 Release the knob and the pilot will remain lit.

6 Turn the control knob dial to the “ON” position.

Notes:

- Activate wall switch to turn the main burner ON or OFF.

- To shut fireplace off completely, depress control valve dial slightly and turn to the “OFF”

position.
