OPERATING INSTRUCTIONS 43
10.2.1 Flame Height and Heat Output Adjustment
Model #SP-34-MV (millivolt system) is equipped with a manual HI/LO
pressure modulator knob, located on the gas valve, for adjusting main
burner flame height and the heat output of the fireplace.
•
Open the control compartment access panel to access the gas
valve and the HI/LO pressure regulator knob.
•
To adjust, turn the HI/LO knob counterclockwise to LO position
or clockwise to HI position, until desired flame appearance and
heat output is achieved.
10.2.2 7 Day Time-out Pilot-on-
Demand Installations
For regions that require installations a 7 day time-out (refer to your
local dealer to see if this applicable to your installation), model #SP-
34-MV is fitted with a millivolt Pilot-on-Demand gas control valve
equipped with a timer set for 7 consecutive days once the pilot has
been ignited. If there is no appliance operation within the 7 days, the
main burner and/or the pilot will turn off,
but the gas control knob will
still be set in its original position (‘PILOT’ or ‘ON’).
•
You must manually cycle the system to reignite operation.
•
This a standard safety feature of the SIT Millivolt Pilot-on-De-
mand control system.
•
Once you turn the pilot on, the 7 day timer will start. If at any
time during the following 7 days your main burner ignites, it will
reset the timer back to 7 days.
To operate your millivolt pilot-on-demand system, open the control
compartment access panel to access the gas valve and gas control
knob. Refer to the lighting instructions on the previous page for
lighting procedures and safety information.
