Installation Requirements
The Town & Country Fireplace installation and venting must conform to the current CAN/CGA-B149 installation code (in Canada) or the current National Fuel Gas Code, ANSI Z223.1 (in the USA), and approved per local codes. Only qualified (licensed or trained) personnel should install this product.
In the state of Massachusetts, only a licensed Plumber and Gas Fitter may install this product.
Manufactured (Mobile) Home
In some jurisdictions, the Town & Country Fireplace may be installed in Manufactured Homes after the "rst sale". Consult local codes for approval. The replace must be fastened in place.
Install in accordance with the current standard Mobile Homes, CAN/CSA Z240 MH (in CANADA), and the Manufacturer's Home Construction and Safety Standard, Title 24 CFR, Part 3280 or the current Standard for Fire Safety Criteria for Manufactured Home Installations, Sites and Communities ANSI/NFPA 501A (in the USA).
Window Frame Removal
Warning: Turn off the replace, and allow ample time for the unit to cool before proceeding.
Caution: The ceramic glass is very fragile, and should be handled with care.
The window frame is held in place by two spring-loaded latches that are operated by a one-piece latch handle.
1. Remove safety barrier screen (Figure 4) by prying the top portion of the screen toward you , then lift the screen from its tabs (inset) located at the base of the window frame.
2. Remove the TC Finishing Touch Trim Kit from the window frame. (If installed)
3. Using a screwdriver (Figure 5) or other similar object, push against the notch in the top of the latch and grab the bottom of the latch handle as it protrudes (Figure 6). Lift handle until latch hook disengages. Repeat for other side while holding glass so it does not tip out.
4. Tilt the top of the window frame out to clear the top edge of the unit. Grasp the sides of the frame and lift up and out to disengage from its bottom track.
5. Place the window frame in a safe place to avoid damage.
6. Re-assemble in reverse order. Latch handle should snap into place and be ush with window frame when engaged correctly.
7. Reinstall Trim Kit if required.
8. Reinstall safety barrier screen
TIP:
To ensure glass is properly latched, grasp the top left and right sides of the glass frame, under moderate pressure it should pull forward and return to original position evenly on both sides.

Locating The Fireplace
In planning the installation for the replace, it is necessary to determine where the unit is to be installed, location of vent system and where gas supply piping may be plumbed. Various installations are possible, such as, into an existing wall, a corner, a built-in wall or a wall projection (Figure 8). Due to high temperatures, do not locate this replace in areas of high trafc or near furniture or draperies.
The minimum clearances from the fireplace to combustible surfaces must be adhered to and are shown in Figure 2 & Figure 3.
EXAMPLES OF COMMON LOCATIONS SEE (FIGURE 14) FOR DIMENSIONS

Note: The fireplace should be in place and venting installed before framing in or building an enclosure around the unit.
The Town & Country replace must be framed in as described below or totally enclosed with non-combustible material, such as facing brick.
Determine the total thickness of facing material to be used. A thickness of 3/4" will allow the nishing surface to be ush with the front of the unit. If preferred, additional masonry type non-combustible material can be installed above and to the sides up to 4 1/2 inches proud of the appliance.
The finishing material must not interfere with glass frame access or movement.
A Steel Stud Framing Kit is supplied with the replace and must be used unless the replace is totally enclosed with non-combustible material. Assemble the framing kit as per the instructions on pages page 11 of this manual. Attach
Framing and Finishing
the steel frame to the replace once the replace is in its nal position. Secure the steel frame to the framing brackets on each side of the unit. Ensure that the studs are set back far enough to allow for thick­ness of nishing surface.
The sides, back and top of the replace can be framed in up to the steel studs and the replace standoffs using conventional lumber. Consult local building codes for specic requirements.
Due to high temperatures, non-combusti­ble backer board, such as cement board or its equivalent, must be used to sheet in the front of the replace, extending 18 3/4" above and 5 " to the side of the fram­ing edge bars (Figure 12). Standard sheet rock (dry wall) may be used beyond this.
If the backer board is not to be nished with other non-combustible material such as tiles, it is recommended that the instructions in (Figure 11) be followed closely.
Chase Insulation: When installing this replace against a non-insulated exterior wall or chase, it is recommended that the outer walls be insulated to same degree as other exterior walls. Do not place replace directly against the insulation. Cover the insulation and plastic vapour barrier with a solid surface, such as dry wall (sheet rock). Consult local codes. Do not insulate or use plastic vapour barrier within the framing kit.
CAUTION: See Figure 11 on page 10 BEFORE PROCEEDING.
NOTE:
The chase must be properly sealed at the ceiling level or between floors in a multilevel installation.
