Combustion Air Supply - Drolet ECO-65 Owner's Manual

1.4.

COMBUSTION AIR SUPPLY

It is mandatory to connect this stove to an outside
combustion air source to reduce the risk of hopper
burn back caused by negative pressure. A insulated
4" inside diameter metallic pipe, either flexible or rigid,
must be attached to the inlet at the stove's rear (refer
to figures 5, 6 & 7). A rodent guard (minimum ¼" wire
mesh) must be used at the terminus (refer to figure 6).
All connections must be secured and airtight by either
using the appropriately sized hose clamp and/or UL-
181-AP foil tape. Also make sure that the fresh air
damper is open while the stove is running. The fresh
air intake damper is located at the back of the stove
right hand side (refer to figure 6.).
For mobile home installations only:
No combustion air supply may exceed 10 feet.
Sources of Outside Combustion Air:
A hole in floor near the back of the leading onto a
ventilated crawl space under the house.
A hole in the wall behind the stove.
