| length. |
¥ | The structural integrity of the manufactured |
| home ßoor, walls, ceiling and roof must be |
| maintained. |
¥ | A manufactured (mobile) home installation |
| must conform with the Manufactured Home |
| Construction and Safety Standard, Title 24 |
| CFR, Part 3280, or, when such a |
| is not applicable, the Standard for Manufac- |
| tured Home Installations, ANSI / NCSBCS |

VENT TERMINATION CLEARANCES
Vertical Vent Termination Clearances
TERMINATION HEIGHTS FOR VENTS ABOVE FLAT OR SLOPED ROOFS
Horizontal Overhang
These instructions should be used as a guideline and do not supersede local codes in any way. Install vent according to local codes, these instructions, the current National Fuel Gas Code
Horizontal Vent Termination Clearances
The horizontal vent termination must have a minimum of 3" (76 mm) clearance to any overhead combustible projection of 2 1/2" (64
mm)or less. See Figure 4. For projections exceeding 2 1/2" (64 mm), For additional vent location restrictions refer to Figure 5.

local codes and applicable state and federal requirements. Familiarity with these requirements before installation is essential. Some important considerations to discuss with local building ofÞcials include:
1.Applicable codes (i.e. Uniform Mechanical Code, State or Regional Gas Codes, National Fuel Gas Code)
2.Local amendments
3.Recognized testing lab:
4.Is a permit required - cost?
5.In some states or municipalities, a licensed gas Þtter or plumber may be required to install this appliance. Check with your local building ofÞcial for requirements in your area (i.e. Is a license required for installation of gas supply line)?
6.Maximum amount of gas pipe without a pressure test - type of test required?
