Water vapor is by-product of gas
combustion.an unvented room
heater prodrces approximately one
(1) ounce (30ml) of water for every 1,
000BTU’s (.3kw’s) of gas input per
hour.
Unvented room heaters are recom-
mended as supplemtal heat (a
room) rather that a primary heat
source(an entire house) in most
supplemental heat applications,the
water vapor does not create a
problem ,in most applications the
water vapor enhances the low
humidity atmosphers experienced
during cold weather.
The following steps will help insure
that water vapor does not become a
problem.
1. Besure the heater is sized prop-
erly for the application,including
ample combustion air and circula-
tion of the air.
2.If high humidity is experienced, a
dehumidifier may be used to help
lower the water vapor content of the
air.
3.Do not use an unvented room
heater as the primary heat source.

       

  A  qualified  service

person  must  install  heater. Follow
all  local  codes.

       

  Never install the

  heater

 

in a  bedroom  or  bathroom

 

in a recreational vehicle

 

where  curtains,  furniture,  clothing,

or  other  flammable objects   are    less
than  42  inches  from  the front, top, or
sides  of  the  heater

 

in high traffic areas

 

in windy or drafty areas

       

   Maintain    the

minimum clearances.  If  you  can,
provide  greater  clearances  from
floor, ceiling, and adjoining  side and
back   walls.

       

  This  heater  creates

warm air currents. These  currents
move  heat  to  wall  surfaces  next  to
heater. Installing heater next to  vinyl
or cloth wall coverings  or  operating
heater  where impurities (such as
tobacco  smoke, aromatic  candles,
cleaning  fluids, oil  or  kerosene  lamps,
etc.) in  the  air  exist, may discolor
walls.

I

 Vent-free heaters add

moisture  to  the  air. Although  this  is
beneficial, installing heater in rooms
without enough ventilation air may
cause mildew  to form from too much
moisture. See Air for Combustion and
Ventilation, pages 5 through 6.

Be  sure  your  gas  supply  is  right  for
your  heater. Otherwise, call dealer
where  you bought  the heater  for  proper
type  heater.
