the right side. Install terminaon cap with the ex-

haust ue collar on the right side.

IMPORTANT: Maximum horizontal vent runs of

24” (609mm) require a 1” (25mm) rise per

12” (305mm) run. Care should be taken when installing

the exible vent pipes to avoid a ght bend that may

cause abrasion or damage to the exible pipes

1. Measure the total chimney length required. If need-

ed, carefully extend the pipes, and cut to the meas-

ured length.

2. Slide the combuson air intake pipe over combus-

on air intake collar (A) and secure with (3) self-

tapping screws (not provided).

3. Place a bead of high temperature sealant around

the base of the exhaust vent collar (B). Slide the

exhaust pipe over the collar and into the high tem-

perature sealant. Secure with (3) self- tapping

screws (not provided). Mark the opposite end of

the exhaust pipe for easy idencaon during the

6.3 Co-linear to Co-axial Combined Venng

IMPORTANT: Maximum horizontal vent runs of

24” (609mm) require a 1” (25mm) rise per

12” (305mm) run. Care should be taken when installing

the exible vent pipes to avoid a ght bend that may

cause abrasion or damage to the exible pipes.

Aer the co-linear to co-axial vent adapter, the co-axial

pipe requires a minimum of 1” (25mm) clearance to

combusbles on all sides of the rigid pipe.

• Maximum horizontal run of 3” x 3” exible pipe

length: 24” (610mm)

• Minimum total combinaon of co-linear and co-

axial vent pipe: 10’ (3.05m)
