DIRECT-VENT FIREPLACE (NATURAL/PROPANE/LP)

®

(B)HDV37N/P AND (B)HDV41N/P

INSTALLATION FOR

HORIZONTAL TERMINATION

1. Determine the route your horizontal

venting will take.

Note:

The location

of the horizontal vent termination on

the exterior wall must meet all local and

national building codes and must not

be easily blocked or obstructed.

Snorkel terminations are available for

terminations requiring a vertical rise on

the exterior of the building (see Figures

10 and 11). Snorkel kit SVK is also

available (see page 15). Follow the same

installation procedures used for standard

horizontal terminations. If installing the

snorkel termination below grade (base-

ment applications), you must provide

proper drainage to prevent water from

entering the snorkel termination (see

Figure 11). Do not back fill around the

snorkel termination.

2. Rigid vent pipes and fittings have spe-

cial twist-lock connections. Assemble

the desired combination of pipe and el-

bows to the appliance adaptor with pipe

seams oriented towards the wall or floor.

Twist-lock Procedure: The female

ends of the pipes and fittings have four

indentations (locking lugs). These lugs

will slide straight into matching slots on

the male ends of adjacent pipes and fit-

tings. (All connections must be sealed

with high temperature silicone sealant

as specified in the second warning state-

ment on page 7.) Push the pipe sections

together and twist one section clockwise

approximately one-quarter turn until the

sections are fully locked. See Figure 12,

page 9.

Note:

Horizontal runs of vent

must be supported every three feet. Use

wall straps for this purpose.

Flexible vent pipe must be installed with

spacer springs every 12". See Figure 12,

page 9. All connections must be clamped

tightly and sealed with high temperature

silicone sealant as specified in the sec-

ond warning statement on page 7.
