MOBILE HOME FLOOR PROTECTION
1 A mobile home floor must be protected against stray sparks, radiant heat build up, or from damage during general
use.
2
This floor protection must meet certain minimum requirements as a thermal barrier. Calculations are provided in
this manual for determining if a floor protector meets minimum requirements for a mobile home installation.
3
At no time should a floor protector be placed on top of carpeting. The carpeting should be removed and the floor
protection should sit directly on the uncovered portion of the mobile home floor. Floor protection should extend to the
front, sides, back, and under the chimney connector as defined for a Model R stove listed in the Floor Protection
Requirements section. In the event there are floor protection questions, contact Country Flame or one of its local
authorized dealers for assistance.
MOBILE HOME CHIMNEY AND DUCTS
1 ALL chimney connectors, parts, attachments, and ducts should meet UL 103HT standards. One of the UL 103HT
criteria is that a chimney component withstands temperatures of 2,100
O
F. Although this UL rating does not guarantee a
chimney fire will not occur, it is as close to ideal as industry standards provide today. 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 excellent chimney manufacturers providing excellent products that meet listing requirements.
From single wall, to double wall, to triple wall chimney components, each type and brand meets many application criteria.
Further, each of these chimney manufacturers 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. Search chimney manufacturer sites like
www.duravent.com .
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 such as a Security Model DL42A, and other parts required by site specific conditions. There will be clearance
differences presented in both the stove and chimney manufacturers’ product literature. ALWAYS use the larger clearance
requirement when installing a wood burning stove system into a home.
4
A mobile home chimney system should serve only one wood burning stove. The chimney system must extend at
least 3 feet above the highest point on the roofline where it passes through the roof. The chimney system should be at least
2 feet higher than any part of a roof or building within a 10-foot clearance around the chimney. Refer to FIGURE 34 for
the 3 by 2 by 10chimney rule. The minimum chimney vertical height is 12 feet and the maximum chimney vertical height
is 25 feet as measured from the top of the Model R to the flue exit. REMEMBER: The structural integrity of a mobile
home wall and roof must be maintained during the installation of the Model R catalytic stove. Country Flame strongly
opposes 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 mobile home chimney kits, such as Dura-Vent’s Mobile Home Kit Number
6DP-MH6” STOCK NUMBER 9096N. These mobile home chimney kits are not all-inclusive. A homeowner should
consult with a certified professional. Additional chimney 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 chimney system and do not deviate from a chimney manufacturer’s
