GENERAL INFORMATION

The VFST and VFPF Series Unvented Room Heaters covered in this manual feature a unit- ized set of eight (8) ceramic fiber split logs.

These heaters have a standing pilot and may be manually controlled through the use of an on/ off wall switch or wall thermostat or any com- bination of both of them.

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 VFST and VFPF Series Unvented Room Heaters must 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 maximum allowable BTU/Hr input of 10,000.
