Indoor Installation

The  heater  is  design-certified  for  indoor  installation
when equipped with the approved drafthood.

Locate heater as close as is practical to a chimney or
gas  vent.  Heater  must  always  be  vented  to  the  out-
side.  See  Vent  Piping  section  for  details.  Minimum
allowable  space  is  shown  on  the  nameplate.  Follow
the  installation  instructions  provided  with  the  Indoor
Drafthood Kit for installation.

Indoor Drafthood

Combustion & Ventilation Air

(Indoor Units Only)

The heater must have both combustion and ventilation
air.  Minimum  requirements  for  net  free  air  supply
openings are one opening that is 12 inches from the
ceiling for ventilation, and one opening that is 12 inch-
es from the floor for combustion air as outlined in the
latest  edition  of  the  National  Fuel  Gas  Code,  ANSI
Z223.1(Canada-CAN/CSA-B149) and any local codes
that may have jurisdiction.

NOTE:

For Canada, indoor installation is restricted

to  an  enclosure  that  is  not  occupied  and  does  not
directly  communicate  with  an  occupied  area.  Refer
to  the  latest  edition  of  CAN/CSA-B149  for  specific
requirements.

Drafthood 

Fig. 6: Indoor Drafthood

NOTE:

The indoor drafthood is optional equipment

and does not come standard with the heater. Use the
following part number: P/N 003723.

All Air From Inside the Building

Each opening shall have a minimum net free area of
130 sq. in.

All Air From Outdoors

When air is supplied directly from outside of building,
each opening shall have a minimum net free area of
33 sq. in.

Vent Piping

Vent  piping  the  same  size  as  the  drafthood  outlet  is
recommended, however, when the total vent height is
at least 10 ft (drafthood relief opening to vent terminal),
the vent pipe size may be reduced as specified in the
National  Fuel  Gas  Code,  ANSI  Z223.1  (Canada  -
CAN/CSA-B149).  As  much  as  possible,  avoid  long
horizontal runs of vent pipe and too many elbows. 

If  installation  requires  horizontal  runs,  the  vent  pipe
must have a minimum of 1/4 in. per ft rise and should
be  supported  at  not  more  than  five  foot  intervals.
Plumbers tape, criss-crossed, will serve to space
both horizontal and vertical piping. Gas vents support-
ed only by the flashing and extending above the roof
more  than  five  feet  should  be  securely  guyed  or
braced to withstand snow and wind loads. We recom-
mend use of insulated vent pipe spacers through the
roof and walls.

For  protection  against  rain  or  blockage  by  snow,  the
vent pipe must terminate with a vent cap which com-
plies with local codes or, in the absence of such codes,
the latest edition of the National Fuel Gas Code, ANSI
Z223.1 (Canada - CAN/CSA-B149).

The discharge opening must be a minimum of 2 ft ver-
tically from the roof surface and at least 2 ft higher than
any part of the building within 10 ft. Vent stack shall be
at least 5 ft in vertical height above the drafthood out-
let.  The  vent  cap  location  shall  have  a  minimum
clearance  of  4  ft  horizontally  from,  and  in  no  case
below, unless a 4 ft horizontal distance is maintained,
from electric meters, gas meters, regulators and relief
equipment.

CAUTION:

Combustion  air  must  not  be

contaminated  by  corrosive  chemical  fumes  which
can  damage  the  heater  and  void  the  warranty.  Do
not  store  chlorine,  bromine,  baquasil  or  acid  in  the
same room as the heater.
