FIREpLACES IN MOBILE HOMES
1.
An outside air inlet must be provided for combustion and must
remain clear of leaves, debris, ice and/or snow. It must be
unrestricted while unit is in use to prevent room air starvation
which can cause smoke spillage and an inability to maintain a
fire. Smoke spillage can also set off smoke alarms.
2.
Unit must be secured to the mobile home structure. Remove
bolts from each side of insert and use plumbers tape to secure
to structure (a washer may be required). Re-install bolts.
.
Unit must be grounded with #8 solid copper grounding wire or
equivalent and terminated at each end with N.E.C. approved
grounding device.

The factory-built fireplace must meet (UM)84-HUD requirements
for outside combustion air supply to the fireplace fire chamber
and the chimney must be listed to UL0 HT or a listed UL-1777
full length six inch (152mm) diameter liner must be used. It must
be equipped with a spark arrestor cap and the outside air must
be installed on the insert. (See Figure 9A and installation

for clearances to combustibles. The label is located on a beaded
chain on the left side behind outer skin.
6.
Floor protections requirements on page 5 must be followed
precisely.
7.
Use silicone to create an effective vapor barrier at the location were the chimney or other component penetrates to the
exterior of the structure.
8.
Follow the chimney and chimney connector manufacturer's instructions when installing the flue system for use in a
mobile home.
NOTE: Offsets from the vertical, not exceeding 45°, are allowed per Section 905(a) of the Uniform Mechanical Code
(UMC). Offsets greater than 45° are considered horizontal and are also allowed, providing the horizontal run does
not exceed 75% of the vertical height of the vent. Construction, clearance and termination must be in compliance
with the UMC Table 9C. This installation must also complies with NFPA 211.
NOTE: Top sections of chimney must be removable to allow maximum clearance of 1.5 ft. (405cm) from ground level for
transportation purposes.
