SECTION I — GENERAL INFORMATION
1.  GENERAL INFORMATION
  The boiler is designed specically for forced draft ring, 
is available with oil, gas or combination gas/oil burners, 
and operates with a combustion efciency of over 80%.
  This manual gives the necessary information for the 
proper installation, operation, maintenance and service of 
units. For special installation problems, contact Burnham 
Commercial, P.O. Box 3939 Lancaster, PA 17604, Phone: 
888-791-3790 .
2.  INSPECT SHIPMENT carefully for any signs of   
 damage.
  A. All Equipment is carefully manufactured,   
    inspected and packed. Our responsibility ceases   
    upon delivery of boiler to the carrier in good   
 condition. 
  B. Any Claims for damage or shortage in shipment   
    must be led immediately against the carrier by   
    the consignee. No claims for variances from, or   
    shortage in, orders will be allowed by the     
    manufacturer unless presented within sixty 
    (60) days after receipt of goods.
3.  SETTING THE UNIT
  Most boilers are equipped with lifting lugs to be used 
in maneuvering the boiler into position. On large boilers, 
where four lifting lugs are supplied, all four lugs should be 
used when lifting the boiler. Scotch boilers can also be rolled 
into position using roller skids under the leg supports, pipe 
rollers may cause damage. The unit should be located in the 
boiler room so as to provide ease of venting and adequate 
clearance for maintenance, serviceability and installation 
of piping.
  The tube pull space listed in the Burnham Commercial 
product catalog must be provided at the front of the boiler.  
The coil pull space must be maintained at the front of units 
equipped with tankless coils. Floor construction should 
have adequate load bearing characteristics to bear the 
weight of  the boiler  lled with  water. A boiler foundation 
is recommended if the boiler room oor is weak, uneven 
or if a water condition exists. These boilers are not for 
installation on combustible ooring. If desiccant package 
was ordered, be sure to remove from the boiler furnace 
using the rear access, and from the waterside using the 
manhole cover.
4.  CHIMNEY OR VENT
  On installations where a natural draft stack is used, 
causing high breeching drafts, the boiler locking blade 
damper (on boilers equipped with one) may require 
adjusting, or one may need to be installed at the boiler 
breeching. In multiple boiler installations, or in installations 
where the breeching draft may vary considerably, automatic 
draft controls in combination with a motorized damper may 
be required.
  When considering the stack and breeching, the design 
should take into account that the boiler/burner combination 
will work best when the pressure at the boiler ue outlet is 
in the range of + or - 1/10 inch WC.
5.  AIR SUPPLY
  A sufcient air supply must be maintained at all times 
to the boiler room for proper performance of the unit. A 
permanent opening or duct should be provided so that 
the boiler input will not exceed 4,000 Btuh/in
2
 of free area. 
Example: Firing Rate (Gas) = 528 MBH
528,000 BTUH = 132 In
2
 Free Area
4,000 BTUH/In
2
Follow local building codes if they exceed these minimum 
requirements.
