Introduction

The

is a direct-vented, 2-sided Gas Fireplace with an 

adjustable burner. It can be converted to both a top vent or side vent 
unit, and it is available in two models:

 Model

(continuous pilot)

 Model 

M40DV-ST-I

 (intermittent pilot)

 Model 

M40DV-ST-F

 (SIT Electronic)

 Model

 (mobile home)

For  Mobile Home Approved Models See Appendix B 

This manual covers installation, operation and maintenance. Light-
ing, operation and care of this fireplace can be easily performed by 
the homeowner. However, all installation and service work should be 
performed by a qualified or licensed installer, plumber, or gasfitter 
who is qualified or licensed by the state, province, region, or govern-
ing body in which the appliance is being installed.

This manual covers both models and unless otherwise specified, the 
designation M40DV-ST refers to both models. Sections which are 
specific to a particular model are marked with a 

      symbol,

plus the appropriate model number.
The M40DV-ST is rated for:

 Natural Gas at 30,000 BTU/H (8.79 Kilowatts) max. input, and 

24,000 BTU/H (7.03 Kilowatts) min. input.

 Propane at 30,000 BTU/H (8.79 Kilowatts) max. input, and 

24,000 BTU/H (7.03 Kilowatts) min. input.
