GENERAL INFORMATION
The CFST and CFPF Series Unvented Room
Heaters covered in this manual feature ceramic
fiber split logs which glow realistically when the
heater is operating.
These heaters have a standing pilot and are
manually controlled through the use of a milli-
volt gas valve.
A spark ignition system (piezo) allows the heater
pilot gas to be lit without the use of matches or
batteries and permits operation of the heater
during a power outage.
These heaters are fitted with a specially de-
signed pilot (ODS) which responds to the
amount of oxygen available in the room and
shuts the heater off before the oxygen level
drops below 18%. The pilot can be relit only
when fresh air is available. Refer to the Com-
bustion and Ventilation Air section.
These heaters may also equipped with an
optional battery powered electronic Carbon
Monoxide Safety Shut-Off (COSS) specially
designed to respond to the amount of carbon
monoxide present in the room air. The carbon
monoxide detector will sound an alarm and
shut the appliances off within 30 minutes
when the amount of carbon monoxide present
in the air entering the unit rises above 100
ppm. Time to respond reduces to 15 minutes
maximum when carbon monoxide levels ex-
ceed 400 ppm.
The CFST and CFPF Series Unvented Room
Heaters are designed to be built into a framed
wall.
This heater has been tested to the standards of
ANSI Z21.11.2 unvented heaters.
Do not install these unvented room heaters in a
bedroom or bathroom as all units exceed maxi-
mum allowable BTU/Hr input of 10,000.
