BUILT-IN FIREPLACE 
INSTALLATION

Built-in installation of this fireplace involves in-

stalling fireplace into a framed-in enclosure. This 

makes the front of fireplace flush with wall. Follow 

the instructions below to install the fireplace in this 

manner. If installing a built-in mantel above the 

fireplace, you must follow the clearances shown 

in Figure 8, page 11. 

Note:

 If desired, purchase a four-sided trim kit for 

built-in installations. See 

Accessories

, page 35.

INSTALLATION

Continued

An  optional  blower  kit  is  available  from  your 

dealer. See 

Accessories

, page 35. If planning to use 

blower, locate fireplace near an electrical outlet.

Minimum Clearances For Side Combustible 
Material, Side Wall, and Ceiling 

A.  Clearances  from  the  side  of  the  fireplace 

cabinet to any combustible material and wall 

should follow diagram in Figure 4.

 

Example: 

The face of a mantel, bookshelf, 

etc.  is  made  of  combustible  material  and 

protrudes 3 

1

/

2

" from the wall. This combus-

tible material must be 4" from the side of the 

fireplace opening (see Figure 4).

B.  Clearances from the top of the fireplace open-

ing to the ceiling should not be less than 42 

inches.

Figure 4 - Minimum Clearance for 

Combustible to Wall 

*Minimum 16 inches from Side Wall 

*

Example

1.  Frame in rough opening. Use dimensions shown 

in Figure 5 for the rough opening.

 

If installing in a corner, use dimensions shown 

in Figure 6 for the rough opening. The height 

is 26

/

8

" which is the same as the wall opening 

above.

2.  An optional blower accessory is available (see 

Accessories

, page 35). There are two options 

for connecting blower to electrical source.

 

Option one:

 Have a licensed electrician install 

a  properly  grounded,  three-prong  120-volt 

electrical outlet at fireplace location. Locate 

outlet inside the framed enclosure. Blower 

power cord will plug into this outlet.

 

Option two:

 Have a licensed electrician con-

nect blower to electrical source at junction box 

inside fireplace.

 

If using option one, have electrical outlet in-

stalled at this time. If using option two, do not 

connect blower to electrical source at junction 

box until step 6.

3.  Install gas piping to fireplace location. This 

installation includes an approved flexible gas 

line (if allowed by local codes) after the equip-

ment shutoff valve. The flexible gas line must 

be the last item installed on the gas piping.

4.  Carefully set fireplace in front of rough opening 

with back of fireplace inside wall opening.

5.  Attach flexible gas line to fireplace gas regula-

tor. See 

Connecting Fireplace to Gas Supply

page 16.
