Elevation is often overlooked when choosing a gas heater, but this important factor can have a major impact on the performance of your heater. Gas acts differently at different altitudes. It is affected by the pressure change as you get higher up. Most heaters will operate normally at altitudes up to 2000 feet, but above that changes often need to be made. At a minimum, the pressure setting in the regulator must be adjusted, but sometimes the gas orifices must also be changed. This will change how much gas is feed into the burner at any given time. Having the right pressure setting and orifices will allow the heater to run more efficiently and heat more effectively.
