Page 9

6.Lift boiler with pry bar. Remove wood blocks. Lower boiler.

C.For Packaged Boiler only, proceed to Paragraph E.

D.Test Section Assembly for leaks before connecting to system and installing controls, trim and jacket. Refer to Figure 3 and Table 3.

1.Plug Tappings C & E (¾ NPT) and Return Tapping B (2 NPT).

2.Insert ¾” NPT x ¼” NPT bushing in Tapping D. Install pressure gauge capable of indicating 50 psi.

3.Insert 2” NPT x ¾” NPT bushing in Supply Tapping A. Install purge valve with a hose that runs to a drain.

4.Connect fill valve and piping to Drain Tapping G.

WARNING

Do not use air to leak test boiler.

5.Fill boiler completely with water by venting air through purge valve. Close purge valve and apply

water pressure of at least 10 psi but less than 50 psi gauge pressure.

6.Examine boiler for leaks or damage due to shipment or handling.

7.Remove plugs from Return Tapping B, Tapping C, and Tapping E (if second limit or operating control is used). Also remove fill valve and piping, purge valve and piping, and pressure gauge.

E.Install special base if installation is on combustible flooring. See Figure 4. Floor shield adds 4¾” to boiler height.

1.Place special base on combustible floor with surface marked “FRONT” in upward position.

2.Locate special base with spacing to combustible materials as shown in Figure 4.

3.Place boiler on special base. Boiler must rest inside locating brackets. Boiler jacket panels will overhang special base.

4.Do not enclose boiler (including special base) on all four sides. Models 805H - 807H may be enclosed on three sides (alcove) while maintaining clearances shown in Figure 4.
