OUTSIDE AIR KIT (MODEL AK-6)
The installation of an outside air kit should be installed during
the rough framing of the fireplace due to the nature of its
location. Outside combustion air is accessed through the
mobile home floor (Refer to AK-6 Installation Instructions for
details). In some instances, a wall installation is required (see
figure 5).
Note: An AK-6WAI Air Kit must be ordered when a sidewall
installation is required (see accessories on page 11).
FAN KIT ASSEMBLY: VCBK3E
A fan kit assembly is preinstalled in this fireplace. Use of
blowers or fans other than manufactured by DESA voids the
warranty. Fan is operated by simply pressing the rocker switch
in the lower right corner of the fireplace face (see figure 6).
NOTE:
Fireplace must be wired to the house electrical
system in order for fan to operate. This fan system does not
require a wall switch.
Electrical connections are made through the cover on the side
of the fireplace illustrated in Figure 7. Use 14 AWG copper
wire for all connections. Be certain the fireplace is properly
grounded.
CHIMNEY PIPE
The DESA chimney system consists of 12, 18, 24, 36 and 48
inch, snap-lock double-wall pipe segments, planned for
maximum adaptability to individual site requirements. Actual
lengths gained after fitting overlaps must be taken into
consideration (lineal gain) and are given in the following
chart:
There are three vent kits available, which have been specially
designed for common installations in manufactured (mobile)
homes: CPMH-A/AC (8’ Vent Kit), CPMH-A/ACA (9’ Vent
Kit) and CPMH-A/ACB (9’ Vent Kit). The contents of these
kits are listed under accessories on page 11. Most chimney
systems for manufactured houses require a standard straight
installation as described in this section. If an uncommon
offset installation is required, see page 10.
Important: If the height of the chimney assembly exceeds
requirements for transportation of the home, the chimney
installation may be completed after the home is sited.
Note: the termination must always be installed after the home
is sited.
ASSEMBLING AND INSTALLING THE DOUBLE
WALL CHIMNEY SYSTEM
Each double wall chimney section consists of a galvanized
outer pipe, a stainless steel inner flue pipe and a wire spacer.
The pipe sections must be assembled independently as the
chimney is installed. When starting chimney directly to the
fireplace, the inner flue pipe section must be installed first
with the lanced side up. The outer pipe section can then be
installed over the flue pipe section with the hemmed end up.
Press down on each pipe section until the lances securely
engage the hem on the fireplace starter. The wire will assure
the proper spacing between the inner and outer pipe sections.
WARNING:
THE OPENING IN THE COLLAR AROUND
THE CHIMNEY AT THE TOP OF THE FIREPLACE MUST
NOT BE OBSTRUCTED. NEVER USE BLOWN
INSULATION TO FILL THE CHIMNEY ENCLOSURE.
Continue to assemble chimney sections as outlined above,
making sure that both the inner and outer pipe sections are
locked together.
When installing double wall “snap lock”
chimney together, it is important to assure the joint between
the chimney sections is locked. Check by pulling chimney
upward after locking. The chimney will not come apart if
properly locked. It is not necessary to add screws to keep the
chimney together (Exception – see page 9 figure 23).
