12 - PRESSURE TESTING
INLET PRESSURE TEST
1.
The valve has an allen-plug on the inlet and outlet.
2.
Install a barb fi tting on the tap you want to measure.
3.
Light the fi replace, check the pressure.
4.
Turn off fi replace; reinstall plug.
5.
Check for leaks.
13 - FINALIZING THE INSTALLATION
B. FLAME APPEARANCE
Flame appearance is aff ected by several factors including altitude, venting confi guration and fuel quality. Although the venturi setting has been factory
set, adjustments may be necessary for optimal performance and visual aesthetics.
When fi replace is fi rst lit, the fl ames will be blue. Flames will gradually turn yellowish-orange during fi rst 15 minutes of operation. If fl ames remain
blue, or become dark orange with evidence of sooting (black tips), the burner tube venturi may need adjustment. Contact Stellar Hearth.
A. INSTALLING THE MEDIA
NOTE: DO NOT SUBSTITUTE THE SUPPLIED MEDIA WITH ANY
OTHER KIND OF MEDIA WITHOUT WRITTEN APPROVAL OF
STELLAR HEARTH PRODUCTS.
Figure 13A
Place the supplied glass media into the base tray.
Cover the base evenly. Do not use more than the supplied amount.
Do not get any glass media into the pilot area; a hazardous condition
could result!
You should be able to see the burner slightly through the media. If you
can't, push the media back from the burner. Smaller fl ames will result
from too much media over the burner.
Figure 13A
NOTE: The appliance and its individual shutoff valve must be disconnected from the gas supply piping system during any
pressure testing of that system at pressures in excess of ½ psi.
NOTE: The appliance must be isolated from the gas supply piping system by closing its individual manual shut-off valve
during any pressure testing of the gas line at test pressures equal to or less than ½ psi (3.5 kPa).
CAUTION: A LOW PRESSURE READING CAN CAUSE DELAYED IGNITION
NOTE: If inlet pressure reading is too high or too low, contact the gas company.
Only a qualifi ed gas service technician should adjust incoming gas pressure.
