Honeywell TRADELINE VR8345M User Manual

TRADELINE
These universal electronic ignition gas controls are used
in gas-fired appliances with capacities up to 300 cu ft/hour
at 1 inch wc pressure drop [8.5 cu m/hour at 0.25 kPa] for
natural gas. The VR8345M will operate with a direct spark
(DSI), hot surface (HSI) or intermittent pilot ignition. The
control includes a manual valve, two automatic operators, a
pressure regulator, pilot adjustment, pilot plug, conduit
cover and ignition adapter. Refer to the following list for
the VR8345M specifications.

3. The installer must be a trained, experienced service
technician.
4. After installation is complete, use these instructions to
check out product operation.
WARNING
FIRE OR EXPLOSION HAZARD
CAN CAUSE PROPERTY DAMAGE,
SEVERE INJURY, OR DEATH
Follow these warnings exactly:
1. Disconnect power supply before wiring to pre-
vent electrical shock or equipment damage.
2. To avoid dangerous accumulation of fuel gas,
turn off gas supply at the appliance service
valve before starting installation, and perform
Gas Leak Test after completion of installation.
3. When working with a system using intermittent
pilot ignition, do not bend pilot tubing at gas
control or pilot burner after compression fitting
has been tightened because gas leakage at the
connection can result.
4. Always install sediment trap in gas supply line
to prevent contamination of gas control.
5. Do not force the gas control knob. Use only your
hand to turn the gas control knob. Never use any
tools. If the gas control knob will not operate by
hand, call a qualified service technician to re-
place the gas control. Force or attempted repair
can result in fire or explosion.
