7 - NEAR BOILER PIPING

7.3 Safety Relief Valve / Temperature Pressure Gauge

 WARNING

Burn and scald hazard.  Safety relief valve could       

discharge steam or hot water during operation.       

Install discharge piping per these instructions.

!

     

Installation of (supplied) safety relief valve shall conform to 

ANSI/ASME Boiler and Pressure Vessel Code, Section IV.  

• Install furnished safety relief valve using 3/4” pipe 

fi ttings provided with boiler. See Figure 2.

• Install safety relief valve with spindle in vertical 

position.

• Do not install shutoff valve between boiler and safety 

relief valve.

• Install discharge piping from safety relief valve.  See 

Figure 2.

• Use ¾” or larger pipe.
• Use pipe suitable for temperatures of 375°F (191°C) or 

greater.

• Individual boiler discharge piping shall be independent 

of other discharge piping.

• Size and arrange discharge piping to avoid reducing 

safety relief valve relieving capacity below minimum 

relief valve capacity stated on rating plate.

• Run pipe as short and straight as possible to location 

protecting user from scalding.

• Install union, if used, close to safety relief valve outlet.
• Install elbow(s), if used, close to safety relief valve 

outlet and downstream of union (if used).

• Terminate pipe with plain end (not threaded).

7.4 Expansion Tank & Make-up Water

• Determine required system fi ll pressure, system design 

temperature, and system water content. 

• Boiler contains 2.6 gallons (US). Size expansion tank 

accordingly. 

• Consult expansion tank manufacturer for proper sizing 

information. Connect properly sized expansion tank 

(not furnished) as shown in

 

Figure 3 for diaphragm 

type expansion tank. 

• Adjust tank air pressure on diaphragm type expansion 

tanks to match system fi ll pressure. 

• Install air vent (furnished) as shown for diaphragm 

type expansion tank system only.

• Install make-up water connections as show. 
• If pressure reducing valve is used, adjust to match 

system fi ll pressure. 

• Verify clean water supply is available when connecting 

cold make-up water supply to boiler. 

• Use sand strainer at pump if water supply is from well 

or pump.
