- Environment Requirements: Engineered and certified strictly for outdoor, ventilated setups only. Not approved for indoor installation.
- Pressurization: Requires clean pressurized water source supplying at least 10 PSI. Lakes and holding tank feeds require an inline water pump system.
- Hose Sizing Tip: We strongly recommend using a standard 1/2" diameter connection hose between the source and pump. While pumps supply adequate PSI, ignition failures are frequently caused by oversized 5/8" or 3/4" feed hoses.
