codes, with the National Fuel Gas Code, ANSI Z223.1, 

or the CAN/CGA-B149 Installation code (series). This 

unit complies with ANSI Z21.60-2000 decorative gas 

appliance for installation in solid-fuel burning fi replace. 

2.   Installation and repair should be done by a qualifi ed ser-

vice person. Monessen Vented Gas Logs must be installed 

only in a masonry or a UL 127 solid-fuel fi replace with 

minimum  venting  requirements,  see  installation  sec-

tion.

3.   To prevent malfunction, gas log set and fl ue should be 

cleaned at least annually by a professional service person.  

More frequent cleaning may be required due to exces-

sive lint from carpeting, etc. It is imperative that control 

compartments, burners and circulating air passageways 

be kept clean.

4.   A damper clamp must be installed to provide the mini-

mum permanent vent opening to vent fl ue products,

A fi replace screen 

must be in place when the log set is burning. Provisions 

for adequate combustion air must be provided. Adequate 

combustion air usually results in all fl ames curling into

als, gasoline and other fl ammable vapors and liquids.

the gas logs and replace any part of the control system 

and any gas control which has been under water.

13. The gas log set must be isolated from the gas supply 

piping system by closing its individual manual shutoff 

valve during any pressure testing of the gas supply piping 

system at test pressures equal to or less than 1/2 psig 

(3.5kPa).
