Raypak Heaters
Low NOx Heater Model
Low NOx heaters normally have somewhat higher efficiencies and exhibit much lower NOx emissions.
They were developed to satisfy low NOx emissions requirements as first imposed by the South Coast Air Quality Management District in California. Your area might require a low NOx heater. You should consider a low NOx heater in any case.
Heater Hits Max Temperature before Actual Temperature
When automation is controlling the heater the automation temperature and the Raypak heater temperature can be different and the heater can hit its maximum temperature while the water is not yet to that temperature.[1]
The default maximum temperature for the pool and spa can be raised.
See page 28 of the Raypak INSTALLATION AND OPERATION MANUAL
Spa Max Temp – Spa Setpoint Maximum Adjustment
Refer to step one on page 28 to access the program screen. Press the MODE button until SPA MAX TEMP appears on the digital display. Using the UP and DOWN buttons will change the Maximum Temperature Setting to your desired value. The control can be set for a maximum of 107°F (42°C).
Pool Max Temp – Pool Setpoint Maximum Adjustment
Refer to step one on page 28 to access into the program screen. Press the MODE button until POOL MAX TEMP appears on the digital display. Using the UP and DOWN buttons will change the Maximum Temperature Setting to your desired value. The control can be set for a maximum of 107°F (42°C).
Altitude Adjustments
Air is thinner and less dense as the altitude increases. A natural gas or propane heater needs an optimum mixture of air and gas. If the air/gas mixture is incorrect you will have an orange yellow flame instead of a good blue flame.
At higher latitudes the gas needs to be adjusted for the proper air/gas mixture.[2]
- The Raypak Standard Digital is good to 2,000 feet.
- The Raypak Digital low NOx is good to 5,000 feet.
Atmospheric heaters: Rated inputs are suitable for up to 2,000 feet elevation. For elevations above 2000 feet, reduce gas input 4% for each 1,000 feet above sea level, as high elevation reduces combustion performance.
Lo NOx heaters: Rated inputs are suitable for up to 5,000 feet elevation. For elevations above 5000 feet, consult the factory.
