Space Heating

If the water heater is to be used for both water (potable) heating and space heating then the following apply.

•The piping and components connected to the water heater shall be suitable for use with potable water.

•Toxic chemicals, such as used for boiler treatment, shall not be introduced into the potable water.

•The water heater shall not be connected to any heating system or components previously used with a nonpotable water heating appliance.

•When the system requires water for space heating at temperatures higher than required for other uses, a means such as a mixing valve shall be installed to temper the water for other uses in order to reduce the scald hazard potential.

Space heating applications are considered commercial applications for warranty purposes.

Temperature Setting

When using this appliance to provide domestic hot water it is recommended that the domestic hot water temperature be reduced to acceptable temperatures in accordance with local codes. In the absence of local codes it is recommended that the domestic hot water temperature be set to 140º F (60º C) or lower in accordance with UPC 501.6 by using mixing valves or the remote controller for the water heater.

Pumps

Only use pumps of brass or stainless steel construction. Do not use pumps of iron construction as they will oxidize and clog the inlet filter on the appliance.

Pumps circulating water through the water heater must be sized to overcome the pressure loss through the water heater, the heating system, and any additional plumbing pressure losses. The pressure drop curve based on the water heater model is provided in this manual.

Replacement

When replacing an existing space heating application,s water heating source (boiler, tank water heater, tankless water heater etc.) with Rinnai water heaters ensure that the water heaters are sized to adequately provide the necessary BTU input for the desired space heating application. Rinnai water heaters are designed to maintain a constant outlet temperature and will supply only the necessary amount of BTU,s to maintain that temperature. Depending on the application the maximum BTU rating of the unit may not be achieved. Contact Rinnai,s Applications Engineering Department for assistance at (800) 621-9419 ext. 4490.

Iron Components

Do not use Rinnai water heaters directly for space heating applications involving iron radiators or applications with any iron components. Iron components may oxidize creating rust that will clog the inlet filter of the Rinnai,s.

Glycol

If glycol is to be circulated through the Rinnai,s, only use propylene glycol in a 40/60 glycol/water mix ratio. It is recommended that distilled water be used to prevent particulate from clogging the filter.

Glycol is toxic if consumed. Provisions must be made to the piping system to guarantee that glycol will never be introduced into the potable water system.

The glycol solution must be compatible with the following items: copper, brass, bronze, rubber, a 283 micron filter, and any other associated plumbing fixtures. Check with the glycol manufacturer to ensure that the solution will pass through the 283 micron filter.
