General Guidelines (Residential)

Regardless of the venting arrangement that will be connected to the heater, the following general guidelines for venting must be followed:

1.

The installation must conform with local codes or in the absence

 

of local codes with the National Fuel Gas Codes, ANSI Z223.1/

 

NFPA 54, Natural Gas and Propane Installation Code, CSA BI49.1

 

for Canada.

2.

Appliance input ratings are based on sea level operation and

 

need not be changed for operating up to 2,000 feet (609.9m)

 

elevation. For operation at elevations above 2,000 feet (609.9m)

 

manufactured to specified deration condition for Canada and the

 

United States.

3.

The appliance and its appliance main gas valve must be

 

disconnected from the gas supply piping system during any

 

pressure testing of that system at test pressures in excess of ½

 

psi. (3.5kPa.).

 

The appliance must be isolated from the gas piping system by

 

closing equipment shutoff valve during pressure testing of the gas

damage. Clearances from vehicles parked beneath heaters must be maintained. Signs should be posted to identify any possible violation of the clearance distances form the heater in the vehicle areas. Maximum allowable stacking height in storage areas should be identified with signs or appropriate markings. The illustrations and Table on the adjoining page specify the minimum required safe distances from combustibles.

(WARNING) Materials and items, when stored under this heater,

 

will be subjected to radiant heat and could be seriously damaged.

4.

All horizontal venting sections must slope away from the heater at

 

a rate of ¼” per foot.

5.

The total length of vent pipe (horizontal and vertical runs

 

combined, plus the length of the exterior termination) must not

 

exceed 25 feet, and must not be less than 5 feet.

6.

The vent terminal, mounted outside of the building, should not be

 

located above walkways. Condensate produced during operation

 

of the heater could drip onto the walkway and could form ice

 

during cold weather.

7.

Be sure that the venting installation is in accordance with all

 

applicable local codes and recommendations of the local gas

 

company.

8.

DO NOT connect this heater to a separate chimney, and DO

 

NOT common vent with any other fuel burning appliance. Gas

 

appliances must not be connected to a chimney flue serving a

 

separate solid-fuel burning appliance.

9.

Maintain a minimum of 1-inch clearance from combustibles

 

around all vent pipes.

10. Seal all vent pipe connections with high temperature silicone

 

sealant and secure each connection with three sheet metal

 

screws.

Minimum Required Safe Distances from Combustibles

In all situations, the minimum required safe distances from combustibles must be maintained. Combustibles are materials which may catch on fire and include many common items such as wood, paper, rubber, fabrics, etc. Combustible materials such as those noted, and any other combustible materials must not be placed closer to any base or side of the MHT tube heater than the distances noted in the diagrams on the following page. If you have any questions about the minimum required safe distances from combustibles,

or the associated diagrams, please contact your installer, Enerco representative or distributor, of Enerco Technical Products during normal business hours which are Monday through Friday, 8:15 a.m. to 4:45 p.m., Eastern Time.

Telephone: (800) 251-0001 or (216) 916-3000

It is important to keep the minimum required safe distances from combustibles at all times to avoid death, personal injury or property
