The Camco Olympian RV Wave-8 LP Gas Catalytic Safety Heater is an ideal secondary heating source. It produces enough heat to warm 290 square feet of space. The heater operates on low pressure gas and can be wall mounted or used as a portable unit. It is equipped with a 100% safety shut-off valve to prevent accidental non-ignitions fuel discharge. The built-in automatic Piezo electric sparker will last for 20,000 starts. There is no electrical drain or battery connection. The Wave 8 is adjustable from 4200 to 8000 BTU/hr. Catalytic heating is 99.98% efficient (flame type heaters waste up to 45% of all heat produced), resulting in a more efficient and low-cost heat.
