Before you order
- This is a standard-NOx model. Raypak prohibits the sale of non-Low NOx heaters into regions that require Low NOx (certain states, counties and air districts). Tell us where the pool is and we will confirm before you order.
- Each variant is built for one gas type and elevation range (#50 natural gas 0–1,999 ft; #57 propane 0–1,999 ft).
- Confirm your gas type. Natural gas and propane are different units and cannot be swapped after purchase.
- These are freight items. Check that the delivery truck can reach your property and that you have help to move the unit onto the pad. Installation must be carried out to local code by a qualified installer.
- Raypak warranty: 3 years parts and labor on Professional Digital heaters. See the Raypak warranty 100-10000378.
