These heaters are manually controlled. Models
VF4000-CMN-2 and VF4000-CMP-2 feature a
gas valve incorporating a millivolt operating
system.
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.
The VF4000 Series Unvented Room Heaters
may be built into a framed wall, or installed in an
optional oak surround.
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
maximum allowable BTU/Hr input of 10,000.
