List of Most Frequently Asked Questions from Training Sessions


Service and installation must be performed by a trained/experienced service technician.

The Maxitrol regulator should not be operated until the regulator/installation is inspected and approved by the local code authority.


 

1. Can I use a Maxitrol 325L with a VLimiter® vent limiting device in a confined space?

See page 38 of the Maxitrol Line Pressure Regulator Guidebook for more information on VLimiter® vent limiter installations.

 

2. Can you mount the 325L in a position other than upright horizontal and then use an elbow, etc, to position the vent limiter in an upright horizontal position?

No. See Maxitrol Safety Warning Instructions GPR_CSA_2PSI_MI_EN.FR or LPROPD_MI_EN.FR

 

3. Can a vent limiter or a vent limiter with the ball check removed be used outdoors as a rain cap?

No. See page 15 of the Maxitrol Line Pressure Regulator Guidebook for more information on VLimiter® vent limiter installations.

 

4. What is the vent line recommendation for venting a 325L?

See page 38 of the Maxitrol Line Pressure Regulator Guidebook for vent line recommendations.

 

5. Can you use a bushing with the 13A15 VProtector® vent protector?

See Maxitrol Safety Warning Instructions GPR_CSA_2PSI_MI_EN.FR or LPROPD_MI_EN.FR.

 

6. What length of pipe is recommended on the outlet side of the regulator before changing direction?

See Typical Regulators/Manifold Configuration on page 22 of the Maxitrol Line Pressure Regulator Guidebook .

 

7. Can an OPD be field installed to a 325L for use on a 5 psi system?

No. Refer to ANSI Z21.80/CSA 6.22 Standard for Certified Line Pressure Regulators.

 

8. What is Dead-End Lockup?

See page 63 of the Maxitrol Gas Pressure Regulator Catalog for a full list of Definitions.

 

9. What is the maximum allowable lockup pressure?

Refer to the ANSI/CSA Standards. Individual product specifications can be found in the Maxitrol Gas Pressure Regulator Catalog.

 

10. How can excessive lockup pressure affect the appliance’s operation?

See pages 58-59 of the Maxitrol Gas Pressure Regulator Catalog or Online Sizing Program for sizing information.

 

11. Can I use a 12A49 VLimiter® on all 325-7’s?

The 12A49 works with all 325-7’s (325-7, 325-7L, 325-7A, 325-7AL). See page 62 of the Maxitrol Gas Pressure Regulator Catalog to choose a proper vent accessory.

 

12. Can I use the 13A15, 13A15-5, 13A25 vent protectors on outdoor applications rather than a vent limiter?

See pages 12-15 of the Maxitrol Line Pressure Regulator Guidebook for more information on acceptable uses of VLimiter® vent limiters and VProtector® vent protectors.

 

13. What is Imblue Technology®?

Imblue Technology® is an anodized coating that increases corrosion resistance and provides extra protection against the elements for regulators used in outdoor applications. See page 46 of the Maxitrol Gas Pressure Regulator Catalog for more information.

 

14. Where should the Imblue® regulators be used?

The Imblue® Regulator should be used anywhere the conditions cause aluminum to oxidize such as coastal water areas, nothern climates where roads are salted in the winter, roof-tops where airborne salt particles may impact regulators, water treatment plants, and swimming pool areas. More information on Imblue Technology® applications can be found here.

 

15. Why can’t I install a regulator with a VLimiter® sideways or upside down?

See page 14 of the Maxitrol Line Pressure Regulator Guidebook for more information. Or see Maxitrol Safety Warning Instructions GPR_CSA_2PSI_MI_EN.FR or LPROPD_MI_EN.FR for proper mounting positions.
