The Ten Foot Rule
Major U.S. building codes specify a minimum chimney
height above the roof top. The "Ten Foot Rule" is a fire
safety rule and not a draft rule. It is recommended that
you always meet or exceed the "Ten Foot Rule". (Fig.
7)
The key points of the "Ten Foot Rule" are:
1. If the horizontal distance from the chimney to the
peak of the roof is 10' (3 m) or less, the top of the
chimney must be at least 2' (610 mm) above the
peak of the roof, but never less than 3' (914 mm)
in height above the highest point where it passes
through the roof.
2. If a horizontal distance from the chimney to the
peak of the roof is more than 10' (3 m), a chimney
height reference point is established on the surface
of the roof a distance of 10' (3 m) from the chimney
in a horizontal plane. The top of the chimney must
be at least 2' (610 mm) above the reference point,
but never less than 3' (914 mm) in height above the
highest point where it passes through the roof.

Installation

Install Electrical Connection
CAUTION: All wiring shall be done by a qualified
electrician and shall be in compliance with all local,
city and state building codes.
IMPORTANT: To prevent electrical shock, the power for
the home must be disabled. This can be accomplished
by positioning the circuit breaker to off.
The BCMH is equipped with a factory installed FK-12
fan and the EB1 junction box. The fan requires 120V
AC, 60Hz wiring to be run to the left side of the unit.
This should be completed before the fireplace is fin-
ished.
NOTE: Check local building codes to determine if a
junction box is required at the romex pigtail/house wire
connection.
Chimney Setup
Since you have already preplanned the chimney run,
you should know exactly how the installation is to be ac-
complished - how much pipe is required and the type of
termination to be used.
CAUTION: Report to your dealer any parts damaged
in shipment, specifically check the end connection
of chimney sections.
Straight-Up Chimney Installation
To mark the centerline of the flue, put the fireplace in
final position and measure out from the wall 7⁷⁄₈" (200
mm). Mark a spot on the ceiling directly above the
fireplace. Draw a line parallel to the back wall through
this mark. (Fig. 8) Using a plumb bob positioned directly
over centerpoint of fireplace flue collar, mark the ceiling
to establish the chimney centerpoint. (Fig. 8)
Ceiling Chimney Hole
Drive a nail up through the ceiling at the marked chim-
ney centerpoint. Check where the hole will be cut for
ceiling joists and any other obstructions such as wiring
or plumbing runs. If necessary, reposition the chimney
and/or the fireplace to better accommodate these joists
and/or obstructions. Remember: it is not recommended
to cut roof trusses, as the structural integrity of the
mobile home floor, wall and ceiling/roof must be main-
tained.
Cutting the Hole
Cover fireplace collar opening and cut proper sized
chimney hole in ceiling. (Fig. 9)
