Gas Input Rate Verification
Natural Gas Input Rate Verification
1. Verify main orifice size. The main orifice body has the orifice hole size stamped on it. NG orifice size shall be #44
(rear b urner) and 3/64" (front burner) for all elevations.
2. Verify that the Manifold Gas Pressure is within 3.5" WC +/- 1/8". Once setup, read the main home gas supply
meter reading.
3. Write the initial reading here >> initial gas meter reading
Turn off all other appliances and their pilot flame in the home.
4. Run this appliance for a period of 30 minutes on maximum flame size. Turn off main burner and pilot
flame. Read the main home gas supply meter reading after the 30 minutes of burn time.
5. Write the reading here >> final gas meter reading
Calculate the following:
6. FINAL GAS METER READING - INITIAL GAS METER READING...Subtract initial gas meter from final gas meter
reading. This will yield the number of Therms used during the 30-minute burn time.
7. Multiply the result in Item #6 by 100,000.
8. Multiply the result in Item #7 by 2. Write down the result here >>
9. The result in item #8 shall be at least the maximum input rate (33,000 Btu/hr) for all altitudes.
LPG Input Rate Verification
Verify main orifice size. The main orifice body has the orifice hole size stamped on it. LPG orifice size shall be #49 (rear
burner) and 3/64" (front burner) for all elevations.
Verify that the manifold gas pressure is within 10.0" WC +/- 1/8".
High Altitude De-Rating
If you are de-rating this appliance at a high altitude, attach the High Altitude De-Rating Label, supplied in the Owner's
Manual Packet, to the back surface of the listing label plate located in the air gap on the side of the Fireplace. If you are also
converting the Fireplace for LP Gas attach the labels included with the conversion kit to the same surface.
Prior to attaching the label, fill in all the information that is requested on the label.
For installations from 610-1370 meters (2000-4500 ft.) the orifice sizes (DMS) for Natural Gas are #44(Rear) and
3/64"(Front) and Propane Gas are #49(Rear) and 3/64"(Front), respectively. See data plate for additional information. For high
altitude installations consult the local gas distributor or the authority having jurisdiction for proper rating methods. If the
installer must convert the unit to adjust for varying altitudes, the information sticker must be filled out by the installer and
adhered to the appliance at the time of conversion."
