Can I use a High Altitude Mobile Home Natural Gas Water Heater in a regular altitude area?
High altitude rating on appliances is determined by gas/oxygen ratio required toburn properly the factory settings on the mixture regulator can be adjusted by a qualified service technician and the gas supply orfice may have to be changed to asmaller diameter this can all be accomplished but the cost of the service call may be more than just getting a appliance sold for your local area
