professional and must conform to the requirements of local, state and federal
authorities
.
2. All gas and propane connections must be leak tested prior to placing into service.
3. Main heater unit (trailer) must not be installed within 12 ft (3.6 m) of combustible materials.
4. All gas Burners are test fired at Ground Heaters, Inc.'s factory prior to shipment.
5. To ensure proper Burner performance and to
avoid machine downtime due to heater sooting, Burner
combustion verification and adjustment must
be performed:
• Before starting at a new job site.
• Before operating at altitudes 1,000 ft (305 m) above or below the last adjustment.
• After any Burner maintenance has been performed.
• After installing any Burner, even if it had been previously used and calibrated.
• If Burner performance is in question for any reason.

be required.
Do not exceed 14 in. water column gas supply
pressure. Excessive pressure will
damage the gas train components.
NG:
Do not exceed 3.0 in. water column manifold pressure, as this will over-fire the
heater and cause damage.
LP:
Do not exceed 2.0 in. water column manifold pressure, as this will over-fire the
heater and cause damage.
