INSTALLATION
Approved Venting Method 3: Existing Chimney System
 Using an existing masonry or factory built chimney for venting is the only other acceptable method
 When connecting to an existing masonry chimney, the cross‐sectional area of the flue must be
considered. A chimney with a flue larger than 6" round (28.27 sq. in.) may require relining with an
approved pellet stove chimney lining system.
 Use an appliance collar where the pellet vent connects to the exhaust output of the pellet stove
and attach the appliance collar to the exhaust blower output using three sheet metal screws.
 Seal each pipe connection joint with high temperature RTV Silicone, to ensure the system is leak
free (Check with the specific pipe manufacturer's instructions before doing so).
 If the pellet vent pipe being used is not a "Twist Lock" system, three (3) sheet metal screws are
required at each pipe joint.
 Connect the pellet stove to outside combustion air using the kit included with your stove or using
an alternative method, as described in the "Outside Air" section, on page 15.

codes.
IMPORTANT! READ AND FOLLOW ALL INSTALLATION AND MAINTENANCE INSTRUCTIONS, INCLUDING CLEANING THE UNIT AS SPECIFIED, AND
ENGLAND'S STOVE WORKS IS NOT RESPONSIBLE FOR ANY DAMAGE OR INJURY INCURRED DUE TO NEGLECT, OR DUE TO UNSAFE INSTALLATION OR
for venting this pellet unit.
 Use Type L or Type PL venting pipe until entering the
existing chimney. Use the appropriately sized adapter when
transitioning from the pellet vent pipe to the masonry or
factory built thimble and be certain that the adapter is
sealed tightly to both the pellet venting system and the
existing chimney.
 Before using an existing chimney, be certain it is in good
condition (A chimney sweep inspection is highly
recommended). Also, make sure the chimney meets the
minimum standards listed in NFPA 211 (A chimney
professional can confirm this upon inspection).
 If connecting this stove to a factory built chimney, it may
ONLY be a 6" flue, UL103 HT venting system (ULC S629 if
Canada). Connection to any other factory built chimney may
result in a poorly operating or dangerous stove installation.

For high altitude installations
(above 4,000 ft.), the vent pipe
should be increased from 3‐inch
(3") to four‐inch (4").
