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

codes. In  the  absence  of  local  codes, use   the

Figure1-Vent-Free   Natural   Gas  Heater

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 supplemental 

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 enhances the low humidity atmosphere 

experience during cold weather. 

WATER VAPOR: A BY-PRODUCT OF UNVENTED ROOM HEATERS

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  combusion  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.
