Compatibility & Installation Notes
Have a qualified installer configure the heater for the available gas supply, size the vent and condensate system, and confirm water and gas pressure. Outdoor use requires the separately sold Rinnai RXOVC vent cap. The included manufacturer thermal bypass valve can support a suitable crossover recirculation layout; follow Rinnai’s piping and pump instructions. Install the BF.HG-34 on the cold-water inlet only. Its limits are 30-75 PSI, 40-100°F water temperature and 9.5 GPM maximum flow. The filter must be included in system flow and pressure-drop calculations; the heater’s maximum GPM is not a guaranteed assembled-bundle flow rate. Keep hot water and thermal expansion from entering the filter. The filter does not replace water softening when required, water-quality treatment, heater flushing or manufacturer maintenance.
For the included filter assembly, see the BF.HG-34 product listing.
Frequently Asked Questions
What comes with this special bundle?
One Rinnai RXP199iN tankless water heater and one Big Frog Supply BF.HG-34 water-heater pre-sediment filter unit. The filter is included at no additional charge while supplies last.
Can this heater use natural gas or propane?
The RX/RXP platform supports natural gas or propane through the manufacturer’s professional setup procedure. A qualified installer must configure and verify the correct gas type; it is not an automatic fuel-switching feature.
Is a recirculation pump built in?
Yes. The RXP199iN has an internal recirculation pump. Confirm dedicated-return or crossover compatibility and control settings with the installer.
Does the free filter replace regular heater maintenance?
No. The BF.HG-34 filters sediment and uses polyphosphate for scale control, but it does not replace heater flushing or the manufacturer’s maintenance schedule. Replace its cartridge as needed for water conditions and usage, no later than one year. Its maximum flow is 9.5 GPM and maximum working pressure is 75 PSI.
Why Buy from Big Frog Supply?
The RXP199iN pairs 199,000 BTU/h input with a built-in recirculation pump, making it a useful choice when hot-water demand and wait time both matter. Compare its pump-equipped design with the RX199iN before ordering; account for the included filter’s 9.5 GPM limit when sizing the finished system.
