Mertik GV30 Series Gas Combination Control Mertik GV34, GV35 GV38 Remote Operated Gas Combination Controls Remote Operated Gas Combination Controls GV34, GV35, and GV38 are battery powered combination controls that need no external electrical power or powerpile to perform all the functions required to regulate, and provide motor controlled gas flow to an appliances main burner. GV34 is configured for on-off low to high main burner function, GV35 on-off main burner function, and GV38 full modulation with temperature controlled main burner shutoff and motor controlled temperature set point. The control is designed for use with a standard thermocouple and ODS pilot, making it a viable alternative to a millivolt type valve. The flame height is controlled by either a hand-held remote or hard-wired wall switch. The ultrasonic remote uses a 9-volt alkaline battery while its receiver, as well as the alternate wall switch, run on four AA alkaline batteries (not included). In the event of a battery failure the flame height adjustment knob may be operated manually so that the unit can continue to provide supplemental heat. Optional side outlet manual burner port, or side manual gas valve with low to high, for decorative burner. Despite its compact size it is capable of a control range of 10,000 85,000 BTU/hr. The main burner can be supplied by both bottom and/or side outlets. Standard Model Remote Remote Receiver
