MOBILE HOME CHIMNEY AND DUCTS
1.
ALL chimney connectors, parts, attachments, and ducts should by TYPE L or PL rated vent. One
of the UL 641 criteria is that a Type L or PL chimney component withstands temperatures that do
not exceed 570
O
F. Mobile home stove and chimney restrictions are that: (a) regular thin walled
stovepipe is not permitted, (b) roof systems cannot be weakened when installing a chimney
system, (c) a chimney cap and spark arrester are mandatory, and (d) the chimney must be strong
enough to withstand normal area wind velocities.
2.
There are many vent pipe manufacturers providing excellent products that meet government
listing requirements. Each type and brand meets many various application criteria and has
specific installation requirements. Further, each chimney manufacturer provides excellent written
instructions on HOW TO install a chimney system. This information should aid the homeowner
in ensuring a certified professional completes the job properly. If there are questions, contact
Country Flame or a local authorized dealer. If additional information is required, a search of the
internet will provide plenty of valuable information. An example of an informative and excellent
vent system site is

.
3.
A complete chimney system should include a HUD approved spark arresting chimney cap, a
storm collar, a roof flashing, an attic radiation shield (if needed), a chimney support box, a ceiling
finish collar, an approved chimney connector, and other parts required by site specific conditions.
There will be clearance differences presented in both the Harvester and vent pipe manufacturers’
product literature. ALWAYS use the larger clearance requirement when installing a Harvester
system into a mobile home.
4.
A mobile home vent system must serve only one appliance. The vent system must extend at least
1 foot above the highest point on the roofline where it passes through the roof. The vent system
should be at least 2 feet higher than any part of a roof or building within a 10-foot clearance
around the chimney. The minimum chimney vertical height is 8 feet and the maximum chimney
vertical height is 25 feet as measured from the top of a specific Harvester model stove to the
chimney flue exit. REMEMBER: The structural integrity of a mobile home wall and roof must
be maintained during installation of a Harvester stove. Country Flame strongly discourages the
removal or cutting of roof trusses or other structural components of a mobile home in order to
install a stove. Consult local code.
5.
To comply with over-the-road height limitations and to protect the chimney system and roof from
damage remove all above roof chimney parts during transport of a motor home. Use only
noncombustible material to seal all chimney system joints to prevent cold air leakage into a
mobile home. Refer to local codes or with an authorized local Country Flame dealer to obtain the
name of approved noncombustible sealants.
6.
Many chimney manufacturers provide pellet (all fuel) vent system kits that contain basic items.
These mobile home vent systems kits are not all-inclusive. A homeowner should consult with a
certified professional. Additional pellet vent system parts will be required to handle variations in
local codes, site-specific mobile home issues, ceiling height, ceiling slope, roof pitch, attic
insulation, attic height, and surrounding objects. Use a certified professional to install a
Harvester vent system and do not deviate from the vent system manufacturer’s installation
instructions. Contact Country Flame or a local authorized dealer to resolve any questions or
installation procedures. TABLE 4 shows the required components needed for a typical mobile
home installation. Contact Meta-Fab (
