you MUST check local building codes to determine the
requirements to these steps.

NOTICE: When installing a sprinkler head in a replace

chase, it is recommended to use a sprinkler head with a

sprinkler activation temperature classied as Extra High.

Keep sprinkler head away from vent and chimney.

Chases should be constructed in the manner of all out­side walls of the home to prevent cold air drafting prob-

lems. The chase should not break the outside building
envelope in any manner.

Walls, ceiling, base plate and cantilever oor of the chase
should be insulated. Vapor and air inltration barriers

should be installed in the chase as per regional codes for

the rest of the home. Additionally, in regions where cold
air inltration may be an issue, the inside surfaces may be
sheetrocked and taped (or an equivalent method may be
used) to achieve maximum air tightness.

To further prevent drafts, the wall shield and ceiling re­stops should be caulked with caulk with a minimum of
300 ºF continuous exposure rating to seal gaps. Gas
line holes and other openings should be caulked with
caulk with a minimum of 300 ºF continuous exposure rating
or stuffed with unfaced insulation. If the appliance is being

installed on a cement surface, a layer of plywood may be
placed underneath to prevent conducting cold up into the

room.

than wood.

WARNING! Risk of Fire! Maintain specied air space

clearances to appliance and vent pipe:

• Insulation and other materials must be secured to prevent

accidental contact.

• The chase must be properly blocked to prevent blown

insulation or other combustibles from entering and

making contact with replace or chimney.

• Failure to maintain airspace may cause overheating and

D. Use of Elbows

Diagonal runs have both vertical and horizontal vent as­pects when calculating the effects. Use the rise for the
vertical aspect and the run for the horizontal aspect. See
Figure 4.4.

Two 45º elbows may be used in place of one 90º elbow.
On 45º runs, one foot of diagonal is equal to 8-1/2 in. (216
mm) horizontal run and 8-1/2 in. (216 mm) vertical run. A
length of straight pipe is allowed between two 45º elbows.
See Figure 4.4.

Figure 4.5 shows the vertical and horizontal offsets for
DVP or SLP elbows.

E. Measuring Standards

Vertical and horizontal measurements listed in the vent

diagrams were made using the following standards:

• Pipe measurements are shown using the effective length
of pipe. See Section 12.A (Figure 12.1 for DVP, Figure

12.8 for SLP) for information on effective length of pipe
components.

• Horizontal terminations are measured to the outside
mounting surface (ange of termination cap) (see Figure

4.6).

• Vertical terminations are measured to top of last section
of pipe. See Figure 4.7.

• Horizontal pipe installed level with no rise.

MEASURE TO SHADED SURFACE
(OUTSIDE MOUNTING SURFACE)

F. Vent Diagrams

To replace the rst starter elbow with two 45° elbows,
refer to Figure 4.8. All other 90° elbows can be replaced
with two 45° elbows.

General Rules:

• SUBTRACT 3 ft. from the total H measurement for each
90º elbow installed horizontally.

• SUBTRACT 1-1/2 ft. from the total H measurement for
each 45º elbow installed horizontally.

• A maximum of three 90º elbows (or six 45º elbows) may
be used in any vent conguration. Some elbows may be
installed horizontally.

• Elbows may be placed back to back anywhere in the
system.

• Any 90º elbow may be replaced with two back to back

45º elbows.

• When penetrating a combustible wall, a wall shield

restop must be installed.

• When penetrating a combustible ceiling, a ceiling restop
must be installed.

• Horizontal runs of vent do not require vertical rise;
horizontal runs may be level.

• Horizontal termination cap should have a 1/4 inch

downward slant to allow any moisture in cap to be

released. See Figure 4.8.

Note: The LCOR-DV36IN/RCOR-DV36IN can adapt

to SLP series vent pipe, if desired.

When venting off the top of the unit, use a DVP-2SL adapter
and a minimum 48 inch vertical section of SLP series vent pipe.

A DVP-SLP24 adapter may also be used with a 24 inch
vertical section of SLP series vent pipe.

After the 48 inch vertical section, the venting table rules

must be followed. The rst 48 inch vertical section is NOT
counted as part of the vertical components in the table. It is
still counted as part of the overall maximum run. All venting
table rules for the vent run must still be followed.

Example: DVP pipe 1 ft. min. vertical = 3 ft. max. horizontal
SLP pipe 5 ft. min. vertical = 3 ft. max. horizontal
