Temporary boilers requires a firm foundation or footing. A concrete pad is the best support and asphalt is an acceptable alternative. At a minimum, a stable, well drained, compacted area is required with wood timbers sufficient to support the boiler's weight. The boiler must be blocked-up prior to operation. All weight must be removed from the running gear on trailer-mounted boilers.

All connections, 1.5 and larger, should be flanged. All Piping should be ASTM A -106 Gr. or A-53 Gr. B, SCH 80 or equivalent.

Instrument Air

On larger boilers, instrument air is required to drive the dampers, combustion controls, valves and regulators. Generally, a supply of 1-2.5 SCFM of Dry, clean instrument air regulated to 20-25 psig is sufficient.

Weather Protection

Generally, all rental boilers are equipped with weather protection. However if low temperatures, are expected, provisions should be made to protect the boiler room from freezing. A shelter in front and around the boiler should be considered for the comfort of the operating personnel during inclement weather.

Local Codes

Check local codes for local stack height restrictions, emission limits and other boiler installation requirements.
