PRODUCT FEATURES

SAFETY  DEVICE

A  standard  requirement for all vent-free  room
heaters.  This heater has a pilot  with  an  Oxygen
Depletion  Sensor(ODS)  safety  shutoff  system.
The ODS/pilot  shuts  off  the heater  if  there  is
not  enough  fresh  air.

PIEZO  IGNITION  SYSTEM

This  heater  is  equipped  with  a  piezo  ignitor.
This  system  requires  no  matches, batteries, or
other  sources  to  light  heater.

THERMOSTATIC  HEAT CONTROL
ON THERMOSTAT   MODELS

These    heaters    have    a    control    valve    with    a
thermostat    sensing    bulb.  This    results    in    the
greatest    heater    comfort    and    may    result    in
lower  gas  bills.

LOCAL  CODES

Install  and  use  heater  with  care. Follow  all  local
codes. In  the  absence  of  local  codes, use   the
latest  edition  of  

National  Fuel  Gas  Code  ANSZ223.1,

also  known  as  NFPA  54*.

Water vapor is a by-product of gas combustion. An
unvented room heater produces approximately one
(1) ounce (30ml) of water for every 1,000 BTU’s
 (.3KW’s) of gas input per hour.
Unvented room heaters are recommended as supple-
mental heat (a room) rather than 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 en-
hances the low humidity atmosphere experienced
during cold weather.

The following steps will help insure that water vapor
does not become a problem.
1. Be sure the heater is sized properly for the
application, including ample combustion air and
circulation 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.
