INTRODUCTION

Models M36E(B,H), VM36E(B,H), M42E(B,H) and VM42E(B,H) are vented gas fireplaces that use an electronic gas control valve and electronic ignition system. A 6" B-Type venting system and a listed type vent cap are not supplied but are required for proper operation. See venting instructions on pages 9 and 10.

WARNING: This gas appliance must not be con- nected to a chimney flue servicing a solid fuel burn- ing appliance.

Models M36E(B,H), VM36E(B,H), M42E(B,H) and VM42E(B,H) are factory equipped for use with natural gas and must be converted when intended for use with propane/LP gas. A respective model PCBE-36 or PCBE-42 conversion kit may be purchased for simple conversion to propane/LP gas. See Accessories, page 25.
