Monessen Hearth Outdoor Gas Fireplace - Manual (Page 4)

C o n t ro l s
A variety of controls are available for natural gas fireplace equipment. Most use a simple, continuously burn-
ing pilot light to ignite the flames. To start a fire, you turn a valve, flip a wall switch or use a remote contro l .
Also available are spark ignitions that re q u i re no electricity, electronic ignitions and units controlled by a ther-
mostat. Some gas fireplace equipment has several temperature levels so that you can "fine-tune" your com-
f o rt.
E n e rgy Use
In terms of energy consumption, natural gas fireplace equipment is rated by the amount of British therm a l
units (Btu) used in an hour (Btu/hr). The larger the number, the more fuel is used and the more heat it will cre-
ate. Most vented gas log sets and fireplaces are in the 20,000 to 60,000 Btu/hour range. Unvented pro d u c t s
have an upper limit of 40,000 Btu/hour.
Residential natural gas prices are usually stated in units called "therms." One therm equals 100,000 Btu. So if
your gas log set burns at the rate of 25,000 Btu/hr, and a therm of gas (100,000 Btu) costs 69 cents (the national
average for 1999, according to the U.S. Department of Energy), it would cost about 17 cents to use your gas
f i replace for one hour.
